Richard,
Actually, many people, including myself, feel relaxed and fall asleep during listening to Paralminals. If you know this will happen, you can instruct yourself before you listen that you will get results from the tape even if you fall asleep. Your other-than-conscious mind will still receive the positive messages. You will still reinforce the Release, Notice, Witness, and Respond steps of Natural Brilliance. The steps will soon become natural for you.
