[This kinda happens a lot. When I'm sick too. Btw, it's cold in my room at night time] ?
It could just mean your sleeping with to many blankets. I have the same problem. Mine is caused by me being restless all the time, I roll around a lot and swing my arms, its like I exercise in my sleep! lol. So try to sleep with less blankets or relax more before you to sleep. Hope this helped!
It could be an indication of a few things.
hmm you could move around alot in bed expecially if you have a bad dream or something along them lines, check room temperature is just cool
Ha I do sleep kinda crazy sometimes but I only have one thin blanket =/
Then yeah, its probably just the restlessness.
It means you're too hot.
Maybe you were hot.....?
