Dreaming??

Question

Why do you feel that we have dreams?

Answer 1

To make us realize things we don't in reality

Answer 2

It depends on the type of dream, but it has been proven scientifically that we need dreams or we go insane.  I don't have a cite handy, but I remember reading about a man who had some sickness where he could sleep, but not deep enough to enter REM sleep, and he went crazy.  

Dreams are mostly a way of clearing the mind and strengethening it where the situations we put ourselves in are much like going to the gym - by dealing with things in our dreams we are practicing for real life.  In our dreams, we often play out things we are worried about so that we will know how to handle them if they ever happen.  Sometimes we dream odd things just to clear out repressed emotion, or to give us in our dreams what we can't have for real (like freedom or flight) so that we do get them one way or another.  Sometimes they make no sense at all, where the dream was just "sweeping the floor" of the mind.
