How images are produced in dreams without any light?
547423
dream can simply be defined as a  series of images, ideas, emotions, and sensations occurring involuntarily in the mind during certain stages of sleep. .Dreams do not need light or any other medium to produce images...In psychology there is what we refer to as REM Sleep...Dreams occur when we undergo what we refer to as REM Sleep...REM Sleep can simply be defined as a state of sleep that recurs cyclically several times during a normal period of sleep and that is characterized by increased neuronal activity of the forebrain and midbrain, by depressed muscle tone, and especially in humans by dreaming, rapid eye movements, and vascular congestion of the sex organs -- called also paradoxical sleep, rapid eye movement sleep..Our mind stores images like a computer...We retrieve these images when we undergo REM Sleep(Rapid Eye Movement)...Now...You will say that we do not dream all what we see...This is where your subconcious mind comes in...What your subconscious mind stores is also a part of what you dream...Your subconscious mind is that part of your mind that you are not aware of..You can also say it is that part of the mind that exists but not immediately available to consciousness.When U dream scary dreams,the part of your mind that produces those dreams is the subconcious mind.Your subconcious mind stores your fears and many other aspect of your feelings...Has this been able to decipher the mystery of dreams a bit?

Sounds almost like a plot from the movie "They Live". \n\nDreams can be so abstract yet seem so real at times.  I have vivid dreams at times and they stay with me at times long after I wake up.  Sometimes dreams are just reflection of our Id...our inner psyche...they some time reflect our emotions and our deep inner thoughts.  Sometimes I like it when I have weird dreams...it helps me with my creativity.

Well, dreaming is a process of the mind to sort and process everything that has happened that day and things that your having problems with. If you have been thinking a lot about this then your going to dream about it. Dreams don't have a heavenly symbolic meaning, another words, God, or anything accept your brain, isn't giving you visions of some sort. \n\nYou could have a dream about a car, let's say, but your mind is sorting out something completely diferent, unless it's something that your really thinking about. All the things that is going on all come together to form highly randomn story lines. Randomn thoght make randomn dreams.\n\nWith your case, sometimes good dreams, or any dreams that have feelings linked with them, can leave a big impact, especailly realistic ones, since most dreams aren't that realistic. The piont is, ONLY your mind is making this dream. There probably is a diferent meaning than what the dream was, but your mind has already work what ever was going on out in that dream, so finding out what meanings that dream had would be pretty useless.

Basically, if you're a 'Lucid Dreamer', you can control what happens in your dream, and know when you're dreaming. Lucid Dreamers also see their dreams in color. \n\nas far as I know, there's no way to 'obtain' lucid dreams, you're just born with or without them. I suggest searching it up on Wikipedia for more information. I've provided the link below.

Dreams are of our subconscious mind, therefore they may seem distorted to some, but in actuality are very real parts of our being.  They can be strongly influenced we are facing strong emotions in our life - hence giving you the very real sense of your senses in your dream.  There have been many times that my husband has had to wake me as I was running and crying - left over results of an alcoholic, abusive marriage- he has learned to wake me slowly and gently and then remind me of my surroundings.  So some can be bad.  He also knows there is one where I somewhat purr and he talks to me and I tell him later, that I have to lie at the alter of the Lord and I'm to ashamed to offer any more than this.  He then goes back off to sleep and says within minutes I'll be up writing a story book or poetry or a letter to someone based upon my time in the dream.  Our subconscious can often be a safe outlet for what we cannot consciously do.  Those around us, like my husband have to learn this.  Several times he has woke cussing terrible and swinging his arm and pointing his finger and as I've listened he's been given his Dad what for - something he can't feel he can do in person. So dreams do not have "dream book" meanings - they have meanings to you as an individual.  God will reveal them to you if you ask him. and if he doesn't, then I've learned I don't need to know.

I hadn't heard that before. If they are then it is your own personal truth. I don't think I do believe this statement. Dreams are the minds way of assisting you to sort throught a puzzle or dilemma or problem. Something you might not have even realised consciously that you were pondering. I am talking about the subconscious mind and the unconscious mind. If a dream is not precognitive ie. a vision of a future event (most dreams are not precognitive), then it is a dramatisation by the mind using expressions, images, words etc that are known to yourself. The mind generates a play if you like and you the sleeper are the only audience. So you are the only one who can recognise the images/expressions used in the play to understand what if any underlying message is there. Knowing this then saying dreams are the invention of truth is quite a sweeping generalisation which in fact, does not really tell you anything at all. Sounds like pretentious rubbish to me.

We have dreams possibely since our brains are constantly busy and when we sleep our brains need to do something so it might looked around for events in your life( like flash backs (you know when you remenber something and is played like a video in your head))or somethings you really like and playes it like a movie to make time past so think of it as a movie theater but it's free.

It's bull.  Dreams are vivid expressions of the subconscious, and while scientists may say one thing, dream experts such as Jung and Frued say the total oppositte. I dream in color, don't you?

I had a dream last night…\nPeople who become blind after the age of 6 can see in their dreams, whereas people who are born blind cannot.\n\nAlthough, people who lose their sight at 7+ have very vivid visual imagery in their dreams 20 or 30 years down the track. The content of their dreams is more often about familiar situations, rather than new ones.\n\nDreaming in sound…\nPeople who are born blind however, still dream. Their dreams, containing as much content as sighted people, are experienced by auditory imagery.\n\nThis is due to their lack of Rapid Eye Movement (or REM), which occurs in sighted dreamers, as if they are watching something in their dream. People who become blind, however have REMs of the same intensity as of sighted people.\n\n\nReferences:\nWebb, Jeremy 1995 The Last Word [Internet] London Reed Business Information Limited Available from http://www.newscientist.com/ [Accessed 22 June 2001]\n\nOrey, H (1999) Medi Info Source [Internet] Irvine, California CME Incorporated Available from http://www.medinfosource.com/expert/exp3092799c.html [Accessed 22 June 2001]\n\n\nWriter: Timothy, Camberwell Grammar\nEditor: Caryn Hamburger

Some people dream in colour, some in black and white.  Some people also have stereo sound.  I believe it has to do with which side of your brain is dominant... I think

You have a very active imagination and creative spirit. Sometimes I dream in color, sometimes in monochrome.

if a person has never seen anything before, they're perception of things is quite different than ours. even by touch, they still cannot form images like we do. our dreams consist of everything we've ever encountered, so our imagination cannot be limited.by not having that sense of image your brain relies on other stimuli to interpret their\nenviroment.

The answer, simply put, appears to be "no." \nBut the answer is YES. A blind person dream as other normal human being does. During dream a person do all those things which he/she imagine. it is only the unconciousness stage of mind.\nThose who are born bilnd cant see images but can only sense like touch,hear,taste,the sensation of moving around, the emotion of joy, etc. But they cant even see colour as they cant differentiate between colours.\nDream images of the blind instead seem to be reconstructions of objects based on sensory input such as touch and sound, just as occurs in waking life. \n\nBut Scientific studies indicate that individuals blind at birth do see visual images; which is still controversial as images are constructs based on input from other senses (and on what the dreamer has been told by the sighted about what these objects look like).\n\nBut those are blind later after birth they have normal dreams as of other normal human beings.
