I agree with Rhewin, before feeling too comfortable with an esoteric explanation you should check that it is not something physical.
In my opinion you should talk to a doctor, one you trust and whom you explicitly tell not to talk with your parents about that yet. Tell him about visual problems, describe the symptoms whithout getting esoteric (he’d get a wrong impression).
Btw, the optician can’t do that much, as he only does very basic tests. Usually they don’t even check for color blindness or 3d issues. In your case it might be something with growth, your blood pressure (yes, really!), your seeing nerves, your visual cortex (oh-oh) and nearly anything else.
Can you explain more about what the light looks like?
Being a practitioner of aura gazing, I would like to say you could be simply one of those people who pick up on auras naturally without having to practice, however you say you only see this light when somebody is moving?
It could just be some sort of visual distortion, but when I gaze at auras and the person moves, I experience the exact same visual phenomena you talked about.
And did you have medical check after you told your doctor about seeing the aura of other persons? What was the result? Or didn’t you simply mention that?
Why would I tell my doctor about my spiritual practice of seeing auras? Anybody can see auras, there is nothing special about the visual phenomena you experience while practicing.
I’m not sure what this white line looks like, and, this is just an idea. But it sounds a bit like tracers. That everything that moves leaves a trail that takes a moment to catch up. This has nothing to do with the eyes. It is a neurological issue, and people who use certain drugs report tracers. It’s like the afterimage which should go away immediately stays a bit longer than it’s supposed to. I don’t know if maybe your description could fit this scenario, though it sounds a bit different, but if it is tracers, it is something to be concerned about because you’re not supposed to have them. You might want to see a neurologist.
Ye, krakatoa has a point. Any hallucinogens could cause this. I think you can get it on your own too (not sure), so be really sinsere about your drug use when you speak to a doctor. I read about this a few days ago… It’s H something… Maybe I’ll remember.
Ok; can you try something for me? Sit down in a quiet room, and take an easily visible object; a rock, lump of wood; nothing to complex to the eyes. If you have a small plant, then all the better; something living would be preferred.
Put the object where you can see it at eye level while sitting. just gaze at it for a while. Not looking directly at it, but just about an inch above it. Blink if your eyes start to dry up, but try to keep your eyes still; staring in the same place. Keep gazing until you seem some luminosity coming from the object.
If you have success with seeing the aura around the object, compare that to the visual phenomena you see when people move. get back to me; with this info, it will be easier to understand exactly what is going on.
Edit: Forgot an important factor; do this against a white wall, or the closest to white as you can get. if you have success with this, I’ll have you do another test, with your hand.
I have no idea about auras, so I’ll just say that it may be something wrong. Check with a doctor, ask in lucid dreams and try and explore all the different ideas you can (The most important one’s being your own)
I did this test a couple of days ago, at home and school, and the aura around the object is the same, except when its stood still it just surrounds the object and doesnt move. ^^
Ok, good; so most likely you are a natural at seeing auras. Now I want you to do something a little more tricky; I want you to get used to viewing the auras of humans and or animals. I would suggest starting with humans, they stay still longer than animals.
Start with getting used to your own aura; hold your hand up to the white wall you used to see the aura of the object you chose last time. Use the same technique, do not gaze directly at your hand, gaze an inch or two above your middle finger. Make sure you hold your fingers apart, not together.
After a while, you might begin to see colors in your aura; this is a good sign, and it means your ability to see auras is advancing. After you have got this down, start gazing at the auras of other people.
I find that the best time to do this is in class; where you sit right behind someone. However, it might be awkward if someone notices you staring, and points it out. Try to find someone who stays in the same spot, and is not too far away.
If you have someone who is willing to sit in front of you for you to experiment with gazing, that would be perfect.
This sounds great! thank you so much I will practice on myself for a while, and then Mr Vokteraven the Dragon has kindly said he would sit in a spot and help me with this experiement
I will let you know as soon as I can when I see things advance with myself, and when things advance with others again, thank you so much for this
Sorry to say, that is completely normal. Afterimages are caused when the cells in your eyes receive too much of a certain color; they then stop sending that color’s signal to your brain for a while. A white surface amplifies this effect since white sends all colors of light into your eyes at once, and the colors you have adapted to are edited out, changing the appearance.
This test works in exactly the same way; using afterimages. No matter how you hold your hand, you will see the same effect on the wall. Other people will produce the same effect. While afterimages are interesting illusions, there is nothing remotely mystical about them. Sorry.
Hehe, auras are not the same as after-images. After some time, you begin to see colors and shapes in the aura that change and fluctuate with the person. One can manipulate the aura with certain practices, and this is a visible phenomena.
But you are right in the idea that there is nothing mystical about them.

Hello again I have done this several times now with objects, and I tested it with Vokteraven. He has a bluey kind of aura, when his body was against a white background.
Im guessing that different colours resemble different moods or personalities or something? xP
From what I know, blue means calm and content. But Im sure it has other meanings too
