Did you ever dream you were dreaming? And then dreamed you woke up? And then realized you were still dreaming? And wondered if you're dreaming still?
One Post Crosser asks, "Am I really writing this card or do I just think I am writing this card or do I think I think I am writing this card?"
While another wonders, "Have you ever wondered if your dreams are, in fact, when you are really awake and what you see around you now is a dream?"
Post Crossers discover dream theory and recursive imagery, all in the same day. My head hurts again.
