I'm rather lost as to where I should begin with lucid dreaming. I have been lucid before, once or twice, and I believe last night I knew I was in a dream, but I made myself wake up. Perhaps it was a nightmare.
I had perfect dream recall afterwards, so I think a journal is a good idea. I'll start one. From what I read in the OP, I should also start doing reality checks often, such as pinching my nose and trying to breathe.
I want to explore the inner workings of my mind and converse with my subconscious, but it seems hard to do. I feel like some sort of step-by-step guide would help a lot, but I know it's different for each person.
