I'm always looking for resources about lucid dreaming, which is why I was delighted when I found The Lucid Dream Exchange. My favorite part of this website is the challenges. During a class, the professor asked students to attempt certain challenges in their dreams. Challenge 0 asks dreamers to go to "infinity and beyond", whatever that means to the dreamer. This is a challenge that I'd really like to try. I also like the challenge of trying to contact someone in a dream.
I really don't know what my version of "infinity and beyond" would be. It's something to explore in a dream. I also don't know who I would contact. It has been years since I have had a lucid dream, but every day I try to be more mindful of the differences between the dream world and waking life. Let's see if I can actually make any progress.
