A suggestion for Lucid Dreamers out there!
I would do this myself but I can't lucid dream fluently yet.
So I was thinking that while in a lucid dream you should sort of summon your dream journal. When you open it, see if it has all your recorded dreams in it. If you read your journal frequently then maybe you'll remember some of the stuff inside it. Now you should read a preferred journal entry. Now see if you've somehow recreated that dream again.
If you ever try this out I'd love to hear the results of it. :banana:
