I have had a few floating experiences in these past three four months. I didn't consciously induced them. It happened in either a lucid dream or when I was aware of sleeping on my bed. I wonder if this floating happened due to my anticipation of floating while in altered state of consciousness. But I definitely was not thinking of floating, since I was sleeping. In this state, thought seems to be able to produce the result right away. So while I have enough energy for floating, the minute I think of floating, I am able to float right up.
