Many times when I wake up , sleep paralysis occurs and I feel as if someone is holding me tightly and sometimes I see someone watching me or screaming at me or talking to me while the sleep paralysis. Also , some times I see strange creatures looking at me from the window or sitting beside me in the bed. I am 14 years old and I am not suffering from any disease. I usually sleep alone in the dark but after what I had been through as I mentioned , I now sleep at light but the same thing happens. This is starting to be very creepy and annoying so please help me.
