What might cause an 81-year-old man to see red dots on the carpet and the walls?

I am 16 years old and I also have this problem, though I would not consider it a problem. It's been happening since I was about six years old. It's very strange to me because i can make mylsef see these red dots. The dots I see are a small cluster of moving bright red dots. It usually occurs in the dark, but also in the light. I think it may just be your mind creating a form of stimulus, though this does not explain how I can cause myself to see these dots. I realize this does not answer your question, but I thought it might help if you knew you were not alone, if we are seeing the same type of dots.

Oh, this is interesting. I do not have this phenomenon anymore but remember that as a child of about 5 to about 7 years I would see red/ blue/ yellow patterns of dots with closed eyes as well. Because my parents had put me on experimental pills back then with tiny traces of LSD to make me less of a day dreamer. I blamed the occurance on LSD.A while ago, however, I read an article on the internet claiming that such visions can be triggered by brain waves going wild. So, possibly LSD after all...:)
