I keep seeing a shadowy figure?

I keep seeing it every night, it's shaped like a hooded human being and every time I see it when I try to look directly at it runs away. It usually happens at 2 a.m and I wake up feeling a pain the back of my head and I start to feel like I'm being watched, and once I've had my laundry basket fall over for apparently no reason. It's been happening for maybe no longer than a week now.
