This happens to me, lots. It could be false awakenings.. When you think your awake but your still fast asleep in bed. Quite often , I will be, say, in the kitchen getting a drink..then I will look at the clock and it will be whizzing around..or look out the window and it be raining stars..or try and turn the light on, and my finger goes through the wall!! Haha

The first few times it can be a bir scary. especially if you go back to your bed and look at yourself sleeping!
