How come i scream when i wake up?

Lol, that's strange! How about telling your mother to stop going into your room and waking you up like that? When your sleep is interrupted that often, especially so early in the whole sleep cycle, it can really mess up your sleeping pattern and be bad for your body in general. I'm no expert, but I just know it's not good to be constantly woken up just when you're about to enter into a deep sleep.
