Last night I was laying in bed, after returning to my body from what I believe was astral projection. All of sudden, I feel as if my body is starting to rise. At the time, I have full control of my thoughts, but I didn't try moving at all. I started to hear a rushing sound in my ears, kind of like a very powerful fan. There did seem to be a light vibration.

I wasn't sure how to proceed. I tried imagining a meadow, but nothing happened. I tried picturing my hands as well, but nothing happened. A weird noise startled me. I tried staying in this state, but the source of what made this noise bothered me, so I willed myself out of it.

I am wondering what I should do next time I'm in this state? This happened to me a month ago, but I got scared that time and didn't allow it.
