I ended up running away from home when I was fifteen (from the house just down the street from the other one funnily enough). To me, this event has signified the biggest change in my entire life. I ran away to an abandoned trailer on the property. It was recently abandoned, so it was in decent shape and had a bed/fridge/running water to it still. I lived there for two weeks and I noticed that the animals around me would act very strange. Animals would circle the trailer and I noticed that owls would situate themselves extremely close to it. Some birds even attacked the trailer. I also noticed that our animals started doing weird things. Merely a month before I ran away, my sister's dog and one of our cats disappeared into the woods in the general area of the trailer at different times. One of our dogs became very agitated while in a field near the trailer. The cat I grew up with (16 years old at the time) suddenly became youthful when she saw me again and actually tried to follow me to the trailer several times (I didn't let her come because I couldn't feed myself much, nonetheless her). This happened the entire two weeks I was there. The spookiest of it happened after about a week when I started hearing heavy footsteps walk through the house right up to the room adjacent to mine. No one was there, obviously. Perhaps a symbolic manifestation of the fact hat I wanted people to find me, but no one searched for even a minute.
Finally, the apartment I currently live in is haunted. I've had a lot of nightmares while I've lived here. I've had sleep paralysis on a couple of occasions and every time my cousin has stayed here, he's mentioned having sleep paralysis as well. Sometimes I can hear people rummaging in my kitchen even when no one is there.
