After watching a movie, when it was over, it totally took me out of my mind. No thoughts were happening. As I sat there, the room and self lightened, seeming less dense. There was no separation between me, the walls, the furniture, and anything in the room. Nothing seemed solid. Everything was blended together, and moving, but as that was happening, fear set in. The moment fear set in, all was solid again.
All that we consider solid forms are forms of space arising in space.
