I believe because I have experienced things that can be explained no other way . My grandfather and father have also experienced things . I think his side of the family have what I call sixth sense and its been passed down to me . It seems only the males in the family have it .
I don't believe in supernatural entities, but I do know people sometimes have experiences that are eerie by setting, behaviour and lack of obvious explanation; and am interested in what those events are both like, and are in fact.
