I grew up in a nice neighbourhood with nice people and a lot of kids my age that I became very good friends with. When nighttime came around though, things would start happening.
The first strange event would happen at night usually between 12:30 and 3:30 in the morning. It sounded like screaming or a cat yelling and would fade in and out. It always started out soft and would build up like something was right on the other side of my window.
This happened for about 4 or 5 years in a row and some nights it sounded like multiple screams, always moving, always changing tones. When it started it scared the hell out of me. I told my mom about it and asked the rest of my family if they ever heard anything and they always said no.
One day while sitting on the couch in the middle of the day it started. I asked my mom who was in the kitchen (next room over) if she heard it and again she said no. After awhile I got used to it, even now it still wakes me up most nights.
A year after I moved out I got a call from my mom saying she finally was hearing the noises I always described to her. I don't think she hears them anymore but she is convinced it was the spirit of their dead cat. Bu why multiple noises on some nights?
