Okay, so one night, I was sitting cross-legged on my bed, and I was meditating deeply. But something odd happened. All of a sudden I felt kind of like I was floating, and I felt like I wasn't in my body, but I couldn't see anything, and my eyes were still closed. Then, I opened my eyes and went back to normal. Did I accidentally go into the Astral Plane or what? Or was a just really tired? Please tell me what happened! Thank You.
