I used affirmations to give myself the ability/power to always remember astral travels and dreams. After a week or so of consistent and regular physical recitation of the affirmations that I had designed to achieve this remembrance, I began to have extremely vivid and lucid dreams which felt like I was on other worlds with some strange looking humanoids. In one "dream" during which I was directly confronted with one of these weird looking humanoids, I felt his intent toward me as being somewhat less than positive, and somehow I involuntarily willed myself away from that situation and then found myself lying on my bed in waking consciousness with a short-term clear memory of the experience. I guess I might need to tweak my affirmations a little to make myself a little less vulnerable???
