Well, this worked for me last night, with some modification. I woke up after 6-7 hours of sleep, then lay back down to sleep. I then relaxed and let my mind wander for about 5 minutes, until I was in that stage where I was getting intermittent hallucinations. Then, I began to visualise a scene, becoming brighter. I turned my attention to my arm, and I could definitely feel both my dream arm and real arm superimposed. I focused on the dream arm, and began to move it forward. However, I didn't get far before it 'snapped back', and could again only feel my real body. I started up a new visualisation, just trying to see a single object this time (I didn't attempt to consciously influence what it would be), and this time, was able to fully separate my dream body from my real body. I was then in a dream, in my bedroom, but my (dream) eyes were closed. I did many nose RCs, to make sure it was a dream (not having eyesight made it harder to spot differences), then sat down on my bed, and attempted to crack my eyes open. I managed this a few times, but each time, I felt like opening them any more would open my real eyes and wake me up, so I stayed blind. When I did crack my eyes open, I saw a sunset through the windows. The dream lasted about 20-30 seconds, probably because I had already slept quite a few hours, and because the curtains are basically useless, so there was sunlight streaming into my real bedroom. Also, I was unable to really do any of the usual stabilising techniques, such as looking at my hands, or examining objects. In hindsight, I should have thought to rub my palms together once I had done the RCs.
