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.

Soul's always been there. You don't get it from anywhere, it don't come from no where. It's always been there. Your question can be interpreted in a lot of ways, gotta be more specific. Where do you think the soul comes from, when do you think we get the soul. Are you a christian, what are you?
