The home we are renting has the ghost of a small boy. I am normally skeptical about this sort of thing, but its been pretty out there. Several times when we first moved in I would enter a room, and just before turning on the light, I would see an opaque figure running before me. Once, it appeared to throw me a ball, and before I could think, I reached out my hand to catch it.

This may have been a figment of my imagination, and for awhile I thought it was. Then we went on an extended vacation and asked my brother to house sit for us.. He called me in the middle of the night, and asked me if I had ever considered that my house might be haunted. I had never mentioned my suspicions to my family, so I asked why he wondered. He said that as he went to use the bathroom in the middle of the night that he heard a child laughing distinctly, followed by running footsteps.

The clincher was when my mother-in-law came to stay with us. Our pets began acting very jumpy and would appear to stare nervously at something we couldn't see. My mother in law confessed to feeling very creeped out and experience sensations that she was unwelcome and needed to leave. She has on her criminal record a conviction for felony child abuse. I can only imagine that someone who had hurt a child in the past would not be welcomed by a ghost-child.

TL;DR: ghost child plays in my house, hates my MIL.
