I get sleep paralysis a lot and I also have ghosts in my house. And one day when my mother and youngest sister were out, leaving me with my father and other sister, I felt myself slipping into what I call 'The state' when sleep paralysis takes over my body. I was in bed, facing the door and as I faced it, it suddenly opened and in came a teenage girl, who had my sisters hair style, and my hair colour (long hair,full fringe, and brown hair) she came over to my bed and said "you promised" before walking out. I had never been so scared in my life. Her face was masked by shadows but I knew for a fact that it wasn't my sister. As soon as she left I could hear giggling behind me "She's scared" I heard a boy mumble "No she's not" a girl replied "Watch," she continued, and in that short moment, I snapped out of the state and ran for my life. I ran to my sisters room and told her everything. She had heard my door open and close but had thought that it was my father. Was is a ghost? An illusion? What happened!?
