I'm visiting a friend right now and some weird things have been going on for a long time now, I've been seeing shadows, hearing footsteps and I've even seen an heard a cat in the house. And my friend has seen and heard things as well, and he heard a deep growl beside him one night and I was sitting five feet from him and I didn't hear it. Earlier today he was outside and he found a mummified cat's claw nailed to a tree in his front yard, it has a weird energy coming from it. I was thinking that maybe that maybe it might be some sort of witchcraft or voodoo and what should be done about it.
