Maintaining a dream journal is a great experience. Helps with lucid dreaming too I'm told. I need to get back into it as well ;)

There's a possibility I'm self-deluding and backfilling my memory, but hard to tell for certain. I never maintained a dream journal.

I don't really believe in dreams as predictions, but someone in a dream recommended a book to me. 

I thought the book didn't exist, that it was a silly dream book. 

Then I ended up buying a book with the same title about a week later as a result of a research rabbit hole.
