Dreams are stories, images and feelings that the mind creates during sleep.  We dream about 2 hours each night, mostly in REM sleep.  We all have them.   

In my dreams, I dream mostly about negative things, eg, crawling through a claustrophobic tunnel, and I do remember them.  
There's also not being able to find my car or fighting off an attacker. The fighting is a human flight or fight response to fear and often manifests itself by my kicking out in the night.  Every once and a while, Joanne finds herself in harm's way and that sets off other explosive responses  :(

I suppose, by remembering some of this alternative reality I feed my creativity.  If only we could somehow record it...

Speaking of recordings, there is none better than Roy Orbison's "In Dreams", which, if we are lucky, Corey will post as his comment :)
