Have been having vivid ones lately.  Apparently so have some of my co-workers.

What do you think dreams are?  For me, I feel like my brain is trying to make sense of things I see/think/do in waking hours.

Except that the other night, I dreamed I was doing laundry with some high school friends.  And not people I'm in touch with now.  People I probably haven't seen for at least five years, if not ten (reunions).

I'd love to hear your theories on dreaming.
