Ghosts

I moved into my boyfriends grandmas house a week and a half ago. I woke up and heard one of the hallway doors close clear as day. I’m home alone I’m freaked out so I locked my bedroom door and lock myself in the bathroom. I was so freaked out I worked up the guts to check the house no one in my house and doors are locked. My baby daddy shows up with my daughter I get dressed and when I’m about to walk out of the room I heard something creak from my bathroom. I thought someone broke in but I think we have ghosts. I never been so scared in my life.
