I read a good book before I go to sleep so I have something to think about as I'm falling asleep.

I've asked "questions" I want answered in dreams before I go to sleep or I've come up with symbols I want to see representing answers :-) I was in a dream group before and we were trying to all dream the same symbols (all dream about "grapefruit" for example) and trying to do that or anything with another, especially a good friend you're close to is fun. We could do that here. But focusing on something before sleep is fun to try.
