Sleep Paralysis And Paranormal Experiences

When I was 14 I had my first sleep paralysis experience. This happened a month into living in a new apartment. The apartment had three rooms and small hallway. I woke up in the middle of the night and had both an out of body experience combined with sleep paralysis. Still laying in bed, I knew that the hallway light was on yet my family was not awake. I heard running up and down the hallway and children laughing one second then crying the next. Then there was silence and I was laying in bed with my eyes feeling the door open and a creature walk in. I say creature because whatever it was it was not human. My body would not let me open my eyes no matter how much my mind told me it was only a dream. I tried to convince myself it was only a nightmare as I felt them come closer until they were looking right at my face. I kept my eyes shut but could feel its breathe on my face as they watched me. They suddenly left. My body relaxed for a second before I felt myself lifted out of my room and taken to my brothers room. Only that it wasn't really my brothers room. They had bunk beds and the room I was put in was barren with mattress in the middle of the room. I suddenly awoke in my own bedroom. I didn't sleep after that for the rest of the night. A week later I decided to finally tell my mother about the experience. She listened then told me she wasn't surprised at all as she had had a similar experience. She said she had heard the running up and down but she had gotten up because she felt a presence in her room. She opened her closet and saw a child crying in the corner. She then said she woke up for real. My family has had previous experiences with spirits including that of a man my mother and I thought was impersonating an uncle who had died as a child. This "haunting" happened to my great grandmother in Mexico up until her death a few years ago. We believe a spirit took advantage of the loss of her child to feed on her suffering. She would say he would sit next to her on the bed and peer in through the windows at night. My mother and I saw someone peering in the window one night but it was not a child. We saw the shadow of a man standing outside our second story window. There was no ledge for anyone to stand on and no one at the window yet there was a shadow on the wall of a man. In both of these experiences my mother and I had no clue about the previous story of the places we were in. We didn't know my grandmother thought she was being taken care of by the spirit of her son. We also had no clue that the previous tenants of our apartment had been a women that physically abused her many children until she was arrested and her children put into foster care until our landlord told us about her own experience. I still have sleep paralysis but haven't talked to a doctor about medication because I don't believe I had an experience in which my life has been in danger. I feel sad for the many spirits trapped in places but I do not expect any harm from them.
