I have this before during my kundalini experience and it happened again last night. I woke in bed to see my linen rippling like waves, or snakes crawling all through them. It is very strange feeling. There is that same feeling of synch when your moving the wheel so it is pk related. It certainly freaks you out though. I had my roof fan on last night so maybe i had synched in with it and so drew energy from it to cause waves, or maybe it was all me. This and spontanious muscle movement tend to go together. Its a response to chi build up maybe. Large scale effects are definitly possible using the same technique as the wheel it is just a matter of being in the zone.
I have experienced something similar when lying in bed my mind somehow sinced with the oscilation of the fan with lightly disturbing results. Even though my eyes were closed I could see the room all arround me through the feedback effect of the oscillation. As I drifted into sleep it felt as though someone else was there.
