You're Scaring Me - Shut The Door

I was working a long day at my factory job; it was around 1 AM when I got home and 2 AM before I got into bed.

The shape of my dad's apartment is the top story of a large building, and there were two windows open: my bedroom and the family room, each on opposite sides of the apartment. My door is shut, clicked, shut. As I am waiting to fall asleep, the door swings open. I find it a little odd, but I blame it on wind. I am kind of annoyed because the hall light is on; however, I ease into laziness and just attempt to roll over to block the light.

As I roll over, the door slams shut. I look at the door, perturbed. Twenty seconds of thinking about it and I blame it too, again on the wind. I try and to forget about it, but the next actions I experienced have changed my beliefs.

The door opens most of the way, slams shut, opens again, and slams shut, and opens one more time. I am petrified and say, "Please stop. You're scaring me. Shut the door!" The moment I say door, the door slams shut, and does not open again. From the middle of the house I could hear mumbling of someone, at least 50 years old and obviously in charge of the house, very confident voice, although I could not understand what he was saying.

The next day I heard a glass move against the granite countertop in a way where you are sure of what the sound is - something totally recognizable.

Has anybody experienced something like this? I doubted the possibility of the supernatural before this terrifying experience.
