Are there ghosts in my house???
I think there are ghosts in my house, I'm a 13 year old from Pennsylvania, my parents built this house 20-18 or so years ago. Funny enough I learned there was an indian massacre across the street from where my house now is. I keep hearing things at night and seeing shadow figure out of the corner of my eye, I've done research and I learned that they aren't demonic. But, there's this other one, its a cat, a shadow cat, its black and has a furry body and tail. But a year ago weird things started happening, I had unforgettable nightmares which I woke up from to feel like something is watching me... Should I be concerned?
(I have a cross in my room and my parents are very religious)
