I have a couple of good ones.
In my old house, the guy who owned it before us blew his brains out in the living room, and my mom was just staring at the wall one night, so I asked her what was wrong. She said there was blood on the wall. So I look, and there are little specks of blood. Not big but they were still there. That was really creepy.
Also in that house, the stairs would creak all the time(not that wierd but scary), and the temp would always change.
My dad's old house, there is SO MUCH bad energy. I'm not sure on the history of the house, but it is one of the oldest houses in my town. It was a big old house, and we used to rent the back of our second floor to college kids, who told us that they saw an old man wearing an army jacket standing in the hall. Creepy part is we went in the attic and there was an old army jacket up there like the college kids saw.
Also, the house had a history of making people REALLY violent. Kinda like the shining but not really. The guy that owned the house before us, who I know and is usually mellow, punched holes in the wall and got really pissed off in it for now reason. such bad karma in the house. You always felt like you were being watched. In fact, we all slept in the living room, my dad included, because we were so creeped out from staying alone in our rooms. That and we had no heat and the fire place was in the living room.
So we sold the house. Funny part is,the guy who bought it called up my dad and asked my dad if "He ever saw anything" in the house. Turns out the wife of the guy has been seeing shadows move around and saw a little girl wearing a blue dress staring at her in the upstairs bedroom.
Creepy shit.
BUT the winning house goes to my friends, whose house's residents in the early 18th century were attacked by indians who murdered and scalped everyone inside, like 8 people total. One woman escaped, but she was run down and murdered in a field by my mom's house.
so yea.
