Creepy

So yesterday morning about 5 min after I woke up I walked from my bathroom to my bedroom and as soon as I stepped into my bedroom there was a constant banging on my bedroom door. At first I thought it was a roommate that normally has to be to work at 6 am needing a ride to work but as soon as I said hello the noise stopped. I opened my door the light in the hall was on but there was no one there I said hello again and my other roommate that was home in her bed told me to look through the peep hole. I then told her the knocking was on my bedroom door. I went and checked the kitchen and living room and out side the door. There was no one there my roommate came out of her room and we checked all the closets as well as the other rooms and no one was there. I then needed to go back in my room and get ready for work but I was too scared to enter my room. Betsy went into my room with me and we said a prayer and then we started getting ready for the day. When I left for work I thought about turning around and going back to the apartment until my roommate left for school but I didn't do it. When I got to work I texted my other roommate and told her to keep the doors locked for her safety when she got home.

The doors where locked but the dead bolt on the front door was not locked. I never heard a door open and close and I always hear the doors open when my roommate that leaves before me leaves. I am not sure what it was but it was totally creepy. It has been more than 24 hours and I am still creeped out.
