Paranormal Experience

I like to watch any t.v. show to do with paranormal, like ghost hunters. The reason I like to watch shows, like ghost hunters, is because when I was a little kid I lived in a haunted house for four years and nobody believed me when I said it was haunted, until one day my brother-in-law was in the shower and he was the only one home. He said that when he got out of the shower he saw someone go towards the back door. So he went to check it out and when he got to the back door, he said he saw something like a dark shadow standing in the corner. He said he ran as fast as he could and he went inside and locked all the doors. Then the blinds in the living room all the sudden went up and he said the lights started flickering on and off.
