That is a great question. I am very interested in the subject and research it all the time. With all of my research, I have to believe that their are ghost and things that go bump in the night. I have had a personal experience with it. About 6 years ago my husband had a little girl named Margret that was following him. I actually saw her with my own two eyes. It was cool but also scary at the same time. When it comes down to the subject of believing or not. I think if you had an experience then you would believe.
