This still makes it sound as if you can actually get an objective movie of a subjective experience. This might work if every dreamscape can be traced back to a very specific sequence of neural stimuli. Record these stimuli and you have the resulting dreamscape. Yes this might work. But I think dreams are more than just neural activity. Neural stimuli might generate the dreamscape to a certain extent, but the aspects which make dreams so unique and personal, are the result of a profound interaction with consciousness, at various levels. The device should therefore be able to measure also the consciousness interactions. I don’t think scientists will ever be able to pinpoint consciousness (and sub/unconsciousness) to specific brain activity. They reason consciousness is the result of brain activity, while I think it’s just the other way round. Which explains why I think it will be impossible to invent such a device.
We might dream more or less the same way, because we all share more or less the same reality model. Therefore, the raw dream structures may be pretty much the same, coloured by our own personal psyche. Change your view on reality and your dreams will alter too.
They happen simultaneously of course, I think the difference is whether your “dream self” controls your eyes, causing them to move in real life, or if your actual body moves the eyes for no reason, causing you to move them in your dream.
LaBerge, etc. did the experiment where they were lucid and deliberately moved their eyes a certain way, and this eye movement was reflected in their actual bodies. Since your lucid dream self can cause your eyes to move IRL, it stands to reason that your non-lucid dream self can cause your eyes to move IRL.
hmm the way I said it did make it sound kinda involuntary… What I meant was, your mind reacts to what happens in your dream by sending your eyes signals to move, thus making them move in your dream world too, rather than just spontaneously moving.
Still, as I’ve already said, I’m no expert .
Experiments have shown that eyes of non-lucid dreamers were following the objets they were dreaming about.
But it is not because eyes move that you can induce to what they see. It’s like a surveillance camera. It moves, but you can not create the image from the movement alone.
Concerning the dream tape, in my understanding, when we elaborate seeing ( in RL and in dreams ), there are thousands of tiny electric variations in thousands of neurons. Their locations are not the same at different time and in different brains. I hardly imagine how we can 1) record them 2) create an image from this information.
I think this will will one day be possible over a long period of time and research. The only way they will be able to have access from information directly from the brain though, is when they find out a way to actually take information from the neurons and somehow transfer that to a computer ( or whatever advanced bio-electronics would be used in that era). They already know how to use electric currents to stimulate parts of the brain… so they just got to figure out how to actually retrieve information directly.
Anyway, it would be cool if that would be possible. I could just see crowding around the TV (or other futuristic media device) to watch a cool lucid dream from the previous night.
Hmm, and if it’s possbile to “slow down” time in your dream (make 3 hours in real time seem like 3 years in dream time), would you need 3 years of videotape to record it on, or would 3 hours be enough? (The movie would seem REALLY REALLY fastforward ^^)
I don’t think it’s possible… because I don’t think that dreaming has anything to do with your brain.
(although I liked the dream machine from prof. Barabas (I don’t know his english name)
First af al, IF dreaming would give the same energy in your brain as the same experience would have in real life. I think it IS possible… Because when you would find out what energy/electronical parts however it is called if we could find out that if someone sees a read dress… it’s the same as braincell number 978562 in group B is active (for the color read) and braincell number 6532 (for the dress) if we could do that, and dreams give the same brainactivity on the same places but only the activity is stopped before it reaches any senses. It would be possible to record dreamings.
(you will have a 3 hour tape with really really fastforward recording on it. If you would dream three years)
But… I don’t think that is true, so I don’t think it’s possible to tape dreams. Why don’t I think it’s true???
Because of the Near Death Experiences people have when there is NO dreamactivity… together with the statement of people who think a Near Death Experience is just a dream…
Although I don’t think that… I think its compareble… It’s just living in an other world inside your brain (in a other dimension) … so I really think dreaming has nothing to do with brain activity, and so also nothing to do with your brains…
If you’ve ever seen the movie “Final Fantasy: The Spirits Within,” one of the first scenes of the movie is the main character having and recording one of her dreams. I just thought that was a worthy comment.
Huh, I am just writing a book where some people invite a device possible to bring objects from dreams to virtual reality. If it is impossible, my book is bullshit… :’( But I believe it is theoretically possible, though it does not necessarily mean it will be done. It is really a complicated task for the science… First, because we still do not know, how the brain really works, in detail. Second, because it must be a device, getting information about the state of every brain cell (and we don’t want to have 10000000000 electrodes stuck into our head, do we?) Third, the deciphering will be different for different people, because it is not necessary that if one person always sees something when having some signal in some center, that another person will see the same thing. So, the system will have to be set up for every person whose dreams are going to be recorded… I am also afraid, that the videotape only, without other feelings, would be not enough to understand somebody’s dream. And if you can translate all the information straight into the audience’s brains… I am afraid, that if such thing is ever invented, dreams will be the last thing the scientist will dream about. But I believe simpler devices will be invented rather soon (thought I don’t think to live as long ), which will just say, without showing the whole picture, what the dream is about… It could help to remember dreams, for example…
Interesting research on the cat. Something about it really doesnt sit well with me but it is certainly interesting.
It doesnt shed much light on just how the brain is supposed to produce consciousness because the visuals the experimenters produce are not the visuals the cat sees. The visuals they produce are on a monitor: where are the visuals the cat sees? Literally everything scientists observe will not be what the cat ACTUALLY sees, only the cat can see that…
But maybe, in theory, a dream record device is possible. Would certainly be interesting. Not sure I’d want all my dreams recorded but maybe some of the better ones. But again, you wouldnt ACTUALLY be seeing the dream itself,you’d be seeing the visuals of it on a tv screen. The emotion of the moment wouldnt be there…
Basically although I find the research interesting, I don’t think it is worth doing considering the ethical questions it raises. Of course that won’t stop it happening…
Poor cat he will go crazy… So many monitors, one inside the other… We will at last know if cats can hallucinate…
Or he will be able to see the next level of reality…
In fact, the quality of the picture will just became worse and worse, because information is lost in all links of the cycle… In several minutes, we will get a gray screen and nothing more…
Perhaps you don’t have to. It seems a neural network can learn the information from another by reproducing his inputs and outputs. So you will have fewer electrods (just 10000000).
it stands to reason that this would work for things hallucianted and therefore dreamed… and i do believe cats dream… i wonder if they had the sense to see if they could see a cats dreams…
By recording the electrical activity of nerve cells in the thalamus, a region of the brain that receives signals from the eyes, researchers from the University of California at Berkeley were able to view these shapes.
The team used what they describe as a “linear decoding technique” to convert the signals from the stimulated cells into visual images.
By being able to tap directly into the brain and extract a visual image the researchers have produced a “brain interface” that may one day allow the control of artificial organs and indeed machines by thought alone. It is also conceivable that, given time, it will be possible to record what one person sees and “play it back” to someone else either as it is happening or at a later date.
…
scary if abused, and surely it will be, right? if we can do it “wirelessly” one day? Right… damn.
Another funny experience about what rats are dreaming :
“The researchers examined REM episodes recorded while the rats slept. About half repeated the unique signature of brain activity that was created as the animal ran. The correlation was so close that the researchers found that as the animal dreamed, they could reconstruct where it would be in the maze if it were awake and whether the animal was dreaming of running or standing still.”
I’ve spent some time thinking about this and I have 2 opinions on the matter:
On one hand, it could be really good for Dream Recall and may unlock some secrets of dreams. You’ll be able to look up dream signs in detail.
But on the other hand, if you buy one and you’re siblings/parents/husband/wife/boyfriend/girlfriend want to know what you dream about, and they hook you up to it without you knowing, they may not like what you dream about. Some things are better left unsaid, same with dreams.
