Is it possible? Yes. I am by no means an expert. Just interested in the "possibility". People who say that they don't believe in ghosts, can NOT believe in the Holy Spirit! (I'll get off my pedestal) Take a digital recorder into the room when no-one else is home. Turn it on and ask questions out loud. Try to get a last name. Snap some pictures on a digital camera. Do both of these in daytime AND at night. Preferable around 3AM. Do not rely on the playback in the tools themselves. Hook them up to a computer and view them from there as some responses will not be heard, or seen at the time of the recording or picture taking.

I know of stories where "ghosts" are being "held" responsible for causing scratches, but to "skin" an animal? They do require energy just to appear. Sounds more like a horrible prank to me. I am an electrician, and there have been times while I was in the basement of an old house and BRRRR!

I would love to be kept up to date with this. Please feel free to Email me if you wish.

The most important item here is the safety of your child. Good luck with it and may God bless.

EDIT:

You may be able to treat this "imaginary friend" as you would your own daughter. Set rules and boundaries. For both of them.
