I definitely believe in spirits.....
I experienced crazy situations at my old house in San Francisco. We lived in a house that was haunted. The previous owner hung himself on the clothesline outside.....Strange things happened so many times it felt like it was part of just living there.
Moms, walked in the bedroom to turn on the light and she yelled and said someone grabbed her hand when she went to turn the light on.....we also used to play darts downstairs outside. One morning we wake up and all the darts were shot all over the outside of the house in random locations that wouldnt be possible for someone to sling on their own.
Random doors closing at night, lights flickering, things like that.
