What is the visual noise when I close my eyes?

Your question is a good one, and you hit on the answer when you call it 'visual noise.'\n\nThe brain is a complex thing.  First off, vision is not a single 'sense' but more like a combination of related senses which work together.  That might seem odd, given that our eyes appear to do the hard work of 'seeing' things such that, without them, we're much worse off where vision is concerned.\n\nYour brain has a region called the 'visual cortex' which is located in the very back of your head.  This region is generally responsible for constructing images and making sense of what your eyes see.\n\nWhen you close your eyes, or enter a very dark room, suddenly there is no more information for your visual cortex to work with.  Its not quite like turning off a camera however.  \n\nYour brain is still quite active. It takes time for your brain to lower its activity.  What you are seeing are the after-images associated with all that former brain activity still playing itself out in your conscious awareness.  Your brain, suddenly starved for signals from your eyes, 'makes up' stuff to account for the small amount of accidental bio-electric activity that still remains.\n\nPerception and awareness are FAR less understood than the actual mechanics of visual stimulation.  Lots of people disagree on how we turn light and electricity/chemicals into mental pictures.  This process, and your perception of it, are still part of the great mystery of consciousness.

A Bang Before You Sleep?\nThe bang you may hear before falling asleep may be the well known phenomenon among the spiritually knowledgeable. The pineal gland may close the circuit int he brain, after relaxing and gliding into the Alpha State (scentifically measurable, slowed brain waves).  Thepineal is the root of the so-called Third Eye, which is activated by the closed circuit. This closing of the circuit can cause us to hear a loud bang as if from a shot or similar. When the Third Eye, one of our 7 main Chakras, stays mainly open and the circuit can flow freely, the bang will rarely  be heard.\n\nWhen you have a cat or dog in the room and consciously hear the spiritual bang, the animal will not move its ears from the bang you hear. This is a sign that it is an inner bang, not a physical event.\n\nThere is much our schools do not teach us, but it is all in books. We only have to rediscover the ancient knowledge.\n\nA good book to read would be Secrets of Chinese Meditation by Lu K'Uang Yu. May be as a second hand book (Internet, Amazon, Barnes and Noble). The second part of the book is full of practical experiences with our spiritual powers.\n\nHappy study.\nCordially, India.Magica

all the mistery is in RBG (red blue and green).\nit really depends in conditions.\nif u r really in a dark place u will see black coz non of the 3 cones (red, blue and green) are activated.\nbut, many time blue, green or red color can be seen for a while of closing eye- that may be because of presence of some light which activates specific cones or bleaching of certain cones- bleaching makes u to see a object even though it is not there.\n NOTE: black is actually not a color because we see it when non of the color cones are activated.\nin addition, we see white when all the color cones are activated.\n  i have a lab (PC) activity for u if u want to know how it works. \ngo to:\nhttp://www.exploratorium.edu/exhibits/f_exhibits.html\nchoose the option mix-n-match. u need to download shockwave to run the programme.

Those noises indicate the adjustment of the pressure inside your middle ear. \nThe middle ear cavity is separated from the exterior by the tympanic membrane, and the only connection of the middle ear with the exterior is by means of a duct connecting this cavity with the back of the nose (the Eustachian tube). This duct regulates the passage of air and is usually closed.\nNow, if the difference between the internal and external pressures becomes too high, the eardrum becomes too tense and does not vibrate adequately, thus sound reception becomes poorer.\nWhen you hear those noises it means that the pressures have been equalized by air entering the middle ear through the Eustachian tube, which is opened by muscles in the throat and palate that contract when swallowing and yawning.\nHowever, permanent/loud/unusual noises could indicate some blockage of the Eustachian tubes; better see a doctor about it.

You're hearing your pulse! The pillow blocks out other noise and you can really hear sounds that are being made by your own body. Happens to me, too. (Happens to most people, I imagine.) But sometimes your head is not in the right position, or there is other noise in the area, or you're really tired and fall asleep quickly, so you don't notice it.\nIf you ever have a chance to be in  Sensory Deprivation Tank, you will hear ALL your body sounds! It is really noisy and can be a bit weird.

When you have unexpect expence your left eye jump and if unexepcted income your right eye jump (this is for male, for females just vice-a-varsa).\n\nBoth eyes jumping you need a nap.

the eyes are dilated from sleep and takes some time for the brain to recognise the light stimuli

When you close your eyes, they naturally roll up a little bit.  This is useful because if your eyelids don't close all the way, it keeps your cornea from being exposed.

I was an insomniac (and sometimes still am) and once a 'sleep doctor' told me this:\n\nWhen light enters your eyes, it stimulates the brain, and tells the body that it is awake. Your brain has to work to process the picture in front of you, even if you've been staring at it for hours. So, with the light stimulation, or even in total darkness where you can't see anything, if your eyes are open, your brain is attempting to process whatever image is, or is not there. Therefore, if your eyes are open and blinking, your brain is working. To sleep, your body needs to be at rest - including your brain. So, when the brain feels that it needs to rest, it forces the body to shut its eyes so that the brain only has to concentrate on the basest forms of work, such as breathing and keeping your heart beating (both of which coincidentally slow during sleep), and will be able to rest due to the greatly decreased amount of work it has to do. As long as your eyes are open, you are thinking too much for it to be able to rest.\n\nI hope that helps. ^_^

I've seen "things" out of the corner of my eye.  Once I was sitting alone in a hospital room (I wasn't the patient, so I wasn't on anything) and someone whispered my name in my ear.  It was very distinct, felt the breath on the exhale, in my left ear.  It was surprising since I was alone watching the Simpsons, but not scary.\nMy brother lived in a haunted house.  If anyone said he was lying when he told them (he was very proud of it), the TV would turn on and flip through all the channels faster than you could on a remote and then shut off.

I am not sure what you mean. Do you mean eyeshine: animal eyes seeming to glow in the dark looking at you? \nCheck out the links to see the explanation for that.

This is true. The computer screen can cause eye strain, thus causing your eyes to want to close. Your brain tells the rest of your body that this is a signal that you are tired and everything else follows suit. To lessen the effect, always have an overhead light on, to reduce the strain on your eyes from the monitor. You can also make your monitor a little darker using the contrast options for a similar effect. Take 10 minute breaks away from the monitor for every hour and a half you are using it.
