How many ghosts have been talked to?

Ghosts can be spoken to, by using a ghostbox which can be purchased from a paranormal store..The voices which can be heard are called EVPs (Electrical Voice Phenomena)..If these EVPs are not of a good quality, they can be filtered on a computer, so you can confirm what the spirits are saying. You can get LOTS of information when using a ghostbox..start off with basic questions like "whats your name?" "Is there anything you'd like to say?"..You may even be lucky enough to have your spirit guide introduce him/herself :)
