I call these semi lucid dreams . . . the key here is remembering previous instructions to yourself, such as relaxing, not showing fear or self doubt, and asking for the message rather trying to control the dream. I have learned over a period of time that I can control my dreams, but so what? . . . more importantly is why do I have these experiences? During he last lucid dream I experienced body separation, left my room, flew around for a while and then started loosing momentum as I ran out of things to try . . . but as soon as I gave myself over and asked (God, the Universe, guides, whatever) what they wanted me to learn or experience, I immediately went into a full blown astral experience . . . there was still a dream scenario as I was taken through a series of lessons and understandings, but I was still in full control and the dream shifted with my thoughts and questions, so I was fully participating . . .
