I Am At One In A World Of Strange, Everything Is The Strange

You know that song from Toy Story...strange things are happening to me? It popped into my head when I thought about this. Had a strange dream..nothing new but it had no connection to what was happening with my body. I layer down to take a nap & in the early process of falling asleep my mouth suddenly opened a small bit & slowly kept opening, which is weird because I never breathe through my mouth unless I have a cold which surprisingly hasn't happened yet...Anyways the strange thing about that is although there was nothing there I felt my tongue flatten on the bottom of my mouth as if something was there & at one point I choked on air. While my mouth suddenly opened I felt something push against my stomach from the inside as if a penis or toy were used. Weirdest thing yet was I felt my head fall like gravity wasn't holding it up....trying to figure out how to explain it...I was laying with my head towards the side as if I was looking at the wall next to me & my head just fell deeper into the pillow...my chin pointed down instead of straight if that makes any kind of sense. Turning this whole thing I did feel my body move on its own but occasionally I do toss & turn so it's not always as if a strange force is prompting me...Never had I felt a forced though. I also got a nasty headache & my stomach hurt for a few minutes after I woke up
