I had accidentally caught one in a trap; he destroyed the trap then followed me home. When it got dark, he came to my house screaming. When the whole family went out on the porch to see what it was, we could hear it right in front of us but could see nothing! Every time I thought of asking my father if I could take his shotgun to see what this thing was the screams got five times louder. I said to myself, 'Whatever this animal is, it can read my mind!' This is a true life experience that happened 55 years ago (1962). Since then I have had one other experience where I knew they were right next to me but I could not see them!" - PeterBerian
