Wikipedia says this:Dreams are the images, thoughts and feelings experienced while asleep, particularly strongly associated with rapid eye movement sleep.

Okay, well that doesn't tell me much.
I read somewhere that when your dreaming and there is some stranger in your dream that you have never seen before is in actuality someone you have seen before. It may have been from your childhood, someone that you saw for only a brief moment, but in that moment your brain registered it in long term memory...or whatever. Weird huh?

There are so many web pages out about dreams, it's hard to discern which one is worthy or not. Dream interpretation varies amongst individuals. It's really what you think your dreams mean.
