This doesn't happen to me; gee my dreams are so vivid, but some people- my mother included- say that they never dream, or can't remember their dreams. Why is this? I have looked it up on the net, but can't find anything on it.
I feel sorry for these people, dreaming is something that I cherish. I sometimes can't wait to go to sleep so that I can get lost in a world free of physical pain and allergies.
