@MLClark I think we creative types have brains that won't turn off. I've found that reading for about a half-hour before bedtime seems to help, for whatever reason.
Last night, I had a dream in which I was recruited by some wealthy person to appear at a private event. When I was returned home, my car had been stolen from the grocery store parking lot where I'd parked it.
Sometimes I think dreams are like Trash Day, when the truck picks up the bin and dumps it all into the pile.
