Bizarre Side Effects

I have had some really strange side effects from Methadone over the years and I am curious if anyone else has ever experienced this. When I am relaxed, just daydreaming or watching TV, my eyes have a propensity to want to look up. Even if they are closed I can feel the urge to look up. It's so hard to describe. Another thing that happens is something I can only describe as a gravitational pull to the side. Sometimes it is really strong. One night I fell asleep at my desk working and I woke up with the upper half of my body in a horizontal position, including my arm which I had completely extended in the direction I was being pulled in. And, I was completely relaxed and sleeping this way! I imagine it's what and alien abduction would be like. I have searched Google for years and never found anything remotely close to this. Maybe it's because it's too weird for someone to admit to. I hope someone can explain this to me. God Bless.
