I used to have a lot of nightmares as a kid, but I stopped getting them. When my dream recall went back up, I started to have (or at least, remember) more of them.
When I was a kid, I remember my dreams everday usually. Nightmares were very common for me. It got me lucid a lot of time and yes, I conquered them all by lucid. 
A big thanks to lucidity.
I do remember my worst nightmare… it’s still stuck in my mind. 
It was about having two friends with me. We were by the wall w/ stairs… and all of a sudden, the most evil-est looking sun came out of the wall and looked at me. I could feel its evil energy and it was about to drag me into the doom. I began to run like hell for my life, but the mysterious force kept on grabbing me and dragging me backward. That nightmare reoccured until one time I finally got to the bedroom and shut the door. I never had that nightmare anymore.
I still remember several of my worst nightmares. I’m glad that I don’t have them anymore. I’m totally fine. I do still have some disturbing dreams, but I wouldn’t call them my nightmares. It’s not that BAD. You know what I’m saying?
hahahaha, Technodreamer. You are very brave for posting that, and I applaud you. Most people would be very disturbed by that imagery, and rightfully so. However, most of our dreams should never be interpreted on a surface level. It’s not hard to look over disturbing images in dreams if you honestly believe that.
I have not had a nightmare since my childhood. I recently posted a MP3 in the Lucidity Centerstage forum under the thread titled “DreamAddict phones into radio show” and I describe some of my nightmares and the simple end to them.
In some of my lucid dreams I have seen what should have been disturbing scenes (like dead loved ones and family members.) The scenes did not have the usual fear or fright that accompanies nightmares. I think after a certain amount of experience with lucid dreams it helps raise your awareness in all of your dreams. I think if I ever did have another nightmare that I would either 1. become lucid and shift the scenery, or 2. wake myself up.
Also had lots of them in my childhood.
I asedk my mother about it, and she told me that I had even more/worse than childs usually have.
In these, I very often was luzid (but kinda on low level). Most of my nightmares were about witches chasing me. The funny thing is, I developed a technique to wake myself (rolling my eyes in a special way). But that always took some time and I was still scared of the witches, so I always tried to run away and hide long enough to be able to wake myself. Sometimes I suceeded, sometimes they just didn´t give me enough time.
Also, one time I had this dream where I had to sneak past a house with a witch in it. Since I knew this was a nightmare I was pretty sure she´d hear me anyway, so I really considered screaming loud so she´d come out and get me, since I knew this would put the dream to an end. I was too scared to really do it, though.
I think the nightmares where the reason for developing lucidity.
Nowadays I very seldom have nightmares, but I´d like to (sounds paradox, but nightmares are usually such intense dream experiences that I like them… as soon as I am awake and calmed down)
edit: I also go by the definition that a nightmare must be scary. If you run away from monsters, but aren´t really scared, then IMHO it isn´t a nightmare
The last one I remember happened some months ago. It was about eating magic mushrooms and getting a bad trip, seeing visions of dead people. That was an really intense one.
It kinda understood that it isn´t real, it had some prelucid feeling to it, but I explained everything with the effect of the mushrooms.

Scientists recommends bedtime prayers
A German scientist says people who suffer from bad nightmares should say their prayers before going to bed.
Detlev Linke, a neuro-physiologist at Bonn University, specialises in sleep disorders.
He says people who suffer from nightmares should try and take control of their dreams.
“With some practice, you can escape from what is tormenting you,” he told the Express newspaper in Germany.
This could mean inventing a good outcome for a recurring nightmare or simply concentrating on other things before falling asleep.
According to Mr Linke, the simplest form of reflection is saying a prayer.
And he says many of his patients have used prayer to learn how to sleep without being disturbed by bad dreams.

Most of my dreams are nightmares.
And for the last week or so I have had too many to count.
I don’t know why I have them,I think it might be becuz the story I’m writing now.
But in a week I would say I have about 5 of the 7 nights.
But damn I love them! 
I used to have nightmares but i don’t get them much anymore. I usually wake up if it gets too scary. My latest nightmare was someone saying “if your nightmare is half as scary as mine…” and then i woke up. The worst one i car remember was when i was i my bed and suddenly it started shaking and i felt a precence behind my bed. Then i woke up scared and confused.
I use to have them quite frequently. Infact, I had one the other night (but the only thing I can remember now was that I was scared).
I quite liked them. For one thing, I use to be able to get lucid (though only for around 5 or so seconds before I woke myself up).
For another, that a strange satisfaction to have managed to eventually escape from some whatever the scary thing. Of coarse they nearly always get you in the end.
And one last thing, my nightmares are perhaps my most vivid dreams ever. And as they quite often take a moive like feeling, it makes them even more coll and dramtic to think about ocne I’ve woken up.
Hey, all this thinking about nightmares has made me remember the one I had the other night 
. It was about ghosts and stuff. It started off quite light hearted (yay, we’ve got ghosts for freinds!) to really terrifying (hey, the dead guys are trying to kill me!).
I didn’t go lucid at all in that one 
.
I don’t tend to get very many nightmares, but looking at my dream diary, I have had two within about one month 
The first involved a fire in a building where I was unable to save both my children - really horrible, but probably an expression of a mother’s worries about her children. That dream stuck with me for days afterwards.
The second nightmare was about some evil spirit being released when I read words in a book. It was really scarey hearing it rushing around outside the building like a fierce wind.
I did have another (rather paranoid 
) dream about an ex-work colleague of mine who was out to assassinate me, but I didn’t feel much fear despite running away as fast as I could. It was more like an exciting computer game than a nightmare.
I WANT A NIGHTMARE!!! I think that the reason why I don’t have them is that I watch so many scary movies, been through REAL scary stuff and I’m just not scared of anything anymore. and even if I am, I face my fears (real OR imaginary)… my life has gotten so boring…i miss my fears…
I want nightmares. They amke you lucid.
THat dream I mentioned earlier. I can’t even remeber it anymore
Speaking of that, I’ve had my first nightmare in ages this night.
It was a ND where I came riding my bicycle and suddently, a bear showed up out of the forrest. At the end of the dream I was terrified but I guess that this is due to a real life event with a bear encounter.
I too miss nightmares, but I won’t say that I wish for more nightmares. I gotta be careful of what I wish for. 
However, lately, I have been having some vivid and odd dreams, but it was more like what SleepyHead said… an exciting computer game rather than an actual nightmare.
Oh well.
One of my close friends has almost nightly nightmares. So much so that he had to get medication from his psychiatrist to prevent them.
But the odd thing is that he has Lucid dreams several times a week whether he wants them or not ever since he was a little boy. He is 37 years old now. . In fact he hates Lucid dreams and says he is unable to stop them.
I can’t help but wonder if maybe there is some kind of connection between nightmares and Lucid dreams. I really don’t know.
I get dreams of worry, sadness and panic. They’re not really like nightmares though. I don’t get really horrible ones that often.
When I was younger (4 or 5), I would have these horrible nightmares about how my house was haunted and things were chasing me and stuff. As you can imagine, it was pretty scary for a 4 year-old. I haven’t had one like that in a while. I’ve had some scattered ones throughout the past few years where people are chasing me, but not really bad.
The majority of my dreams are nightmares… I haev only had a few of recent that wernt nightmares… its been that way all my life though, not sure why.
thats why id like to learn to LD in hopes of being able to confront these.
I think nightmares can be helpful sometimes, like in depressive moments you get a major rush in some dreamworld to wake in fear…not fun, but intense! sometimes I want them, but how can you induce them?
my method for bailing out is simple: focus on shaking an inner part of the head and throat. like your spine. beats SP every time.
the only nightmares i tend to have are recurring right now…
and i ALWAYS force myself awake…
some of them are about people burning… like… for no reason there will be a fire somewhere, and someone burning and screaming… and i run and try and get away from them as much as possible and try not to hear them, and usually force myself awake…
one was this family in a car which was randomly in a neighbors back yard for no reason and randomly blew up (influenced by Goldmember probably) and I was lucid so I wasn’t too upset and poured pool water onto them, and they started sizzling and steaming up and stuff but it wouldn’t put them out…
I freaked out and woke myself up… then later I decided to go reconfront it and with all my will power I managed to extinguish them.
I don’t know if there is a connection but once whilst lucid I was goofing around with fireballs and accidentally burned a little girl, so I tried to heal her but it wasn’t working right… so I apologized and told her I’d come back to heal her… but I never have…
It’s not that I don’t want to anymore, I figure I should give it a try since I said it would, it’s just that I never remember while lucid.
Then a lot of times I have dreams about horror movies, inside video stores… they usually have very disturbing covers… like… really screwed up stuff… like rape/torture and it’s pretty violent… it used to be i’d be looking for porn and i’d stumble accross them…
So more screwed up sex symbolism for me… yay…
But they weren’t really nightmares per se…
This one time recently (semi-lucid) I met this girl at a video store and it was really abstract and freaky looking, and I thought it was pretty cool… she said something about a scary section and it was dark red (like lit up) and I wanted to explore it but just looking at it from afar made me feel really uneasy.
My worst nightmare ever was probably my first FA
I had a dream about being at a babysitters and that she was putting poison in our food and I found out… so then she chased after me… and I woke up and went out in the hallway… and then all of a sudden she was standing right there by me…
It scared me so badly … I mean I was just a little kid and I thought for sure I was awake… man… it was pretty bad.
Then my first episode of SP with a presence involved around 12… it was a grim reaper looking guy with a sword and I thought for sure I was about to die… I prayed (being reilgious at the time) … which was more like screaming inside my head, for help… and I eventually woke up…
I can’t remember if I had them when I was a child, I never had problems with them, and since I’m a natural LD and I have LD’s everynight, I never have nightmares. There are times in my dreams where a situation can become scary, but since I am in control I can just change it. In this way, I am so grateful to have LD’s and dreams are always fun for me. More than fun, amazing.
