Sawlogs is a searchable dream database. These aren't rambling short story length posts, most of the descriptions are brief, to the point and very badly spelled. Not only can you find out what other people are dreaming about, you can rate their dreams on a scale from one to five. If you prefer, enter your dreams so that others can judge them.
I typed in "grandfather" and got this obviously five star dream:
Weird Grandfather Show
Dreamed on 2007-01-12 by Emily Stewart
I was at a type of arena-ish thing but it had balconies like a theatre would. Everything was whit or a lite shade of grey or blue. I was in an act where my grandfather would pretend(im not sure if he was pretending) to go crazy. One point during this "spell" he tooke a piece of my skin , bit it and dragged me around as if he were a dog with a chew toy. I didn't feel in any danger though. I looked up at the balcony and I saw the guy I like looking down and laughing as if he was enjoying the show. I mouthed help me at him and he just laughed, because he knew it was part of the act.
