Don't worry if it takes a few days to get your dream recall up. Remember, you are building new habits, and that can take some time. Also, don't underestimate the power of autosuggestion. Just tell yourself that you will remember your dreams. It sounds silly, but it works really well for most people.

I think Abra is right on with the self hypnosis. It sounds like you are slipping into a state of deep relaxation pretty easily. Keep trying to develop this, because it will be a very valuable skill if you ever start trance induction for WILD or self hypnosis, or any related meditations.
