When you get a little ways into a WILD, you start to lose track of your real body, and replace it with an imagined body. That is the goal, after all, right? During the transition to this stage, you can have some half-awareness where your imagined "dream body" overlaps with your real body. Some bizarre hallucinations can occur, such as body distortions, feelings of motion, ect. I often feel like my head is expanding like a balloon.

Or, you may have just dozed off for a second, and closed your fingers
