A Threatening Presence In My Room

Last week I was alone in my new apartment in downtown Manhattan that I share with my sister. My sister was sleeping away for the week and I was watching TV with a friend. The friend left and I went to go to sleep around 2am. I am not afraid of the dark or afraid of being alone, in fact I prefer to be alone and I prefer to sleep in pitch black - no light at all! I was tucked into my covers very cozy and already half asleep, extremely relaxed and feeling very serene. All of a sudden I heard the loudest bang on the window next to my bed just a couple feet away. Not only did it wake me from my half-sleep but I nearly leapt out of bed. It sounded like a body had been slammed against the window, the only thing is that I have lived on the fifth floor of an apartment building and I have a little balcony but it faces another apartment building - so it is very sheltered and nothing could fall and hit the window or be blown into it easily or at all.

I calmed myself down and told myself it was nothing even though my heart was pounding. I lay still trying to fall asleep, and then it happened again! Just as loud and this time I was already fully awake and alert. After that I felt like something was standing in the room watching me from the corner. I have never been scared of anything before and so I forced myself to lay there almost as punishment for being so "silly and ridiculous". But fifteen minutes passed and I felt the presence getting closer to me. By the end of half an hour I felt like it was right next to my bed leaning over me. My heart was pounding so fast, my whole body on pins and needles and my hair standing straight up. I turned the light on next to my bed, but it didn't help my fears at all or the feeling I had. The presence was so strong that it felt like my head and ears were nearly vibrating from the pressure in the room. I finally ran out into the living room and turned on the TV and positioned myself to sleep on the couch. I didn't fall asleep until 6am, I felt like something was watching me.

I had the same feelings the next three nights and I wasn't able to sleep until finally the fourth night when I climbed into bed I felt a presence again, only this time it was not threatening - in fact it was calming. I literally felt an intense heat up and down and around my legs all the way to my head like a protective force was shielding me. The sensation was so strong that I actually smiled and fell asleep within a couple of minutes. One thing I should mention is that I survived a small plane crash that killed everyone else on board, including my father and stepmother when I was thirteen. Everyone says that an angel or something was protecting me but I was also told that when I was a baby my nannies used to try to use "voodoo" rituals on me, cutting locks of my hair and putting strange things in my clothes and under my pillows. When my mother had finally confronted them about this they confessed that I attracted dark forces and demons and they were intrigued by my spirit. My mother put up with it for years until she became so crazed over it that my father, who thought she was crazy, finally divorced over it! So I have been told I attract demons but given my history, that something also protects me.

Am I crazy? Or does anyone think that what happened in my room the other night was something real, and something hostile. Any advice would be so greatly appreciated! I am literally and figuratively in the dark right now about all this. Thank you so much!
