This is awsome. I'm actually VERY amazed and happy to just read this by coïncidence! Ever since I was a kid, I would see these little "balls" or "spheres" when I was laying in my bed, eyes closed. From what I could tell, they were always blue, white/silver and red. I always thought of them as flying packs of glass Christmas balls. Whenever I would close me eyes, at a certain point these balls would appear out of nothing in the center of my view, packed up in groups. Then either of these two things would happen:
1: The group would get bigger and bigger and the balls would get smaller, and they would race off to the right/left and eventually fade.
2: The balls would become bigger and more clear, and I could distinguish color.
I was never able to control it, and remember getting frustrated when I couldn't make them come back, because I wanted to see them again. My feeling always told me that it had to do with some sort of light, playing tricks on my vision with some sort of after glow. I've also thought of my brain and nerves having some reaction that made me see them.
Anyway, I never bothered to ask anyone else if they saw them too, since I feared they wouldn't understand me and make me out for fool. I have had these weird thoughts in my mind, or sensations in my body that nobody else I've spoken to has, so I thought this was just another weird thing. Makes me smile to read this, even though it's such an insignificant little thing
