Once when i was a teenager a friend of mine and I were driving over the Rio Grande and saw what appeared to be headlights under the water. We stopped to get a better look and got out of his pickup. We soon saw the lights approaching us. we saw a phantasmesque figure flying toward us so we jumped in the truck and drove away. For a few nights I had terrifying dreams about it. I have been compelled to go to whatever river I live by to investigate. Last week I had a dream about it and was again compelled TWICE to walk along the Kings River here near my home. Both nights I heard shrieks and other scary sounds. I take my pistol with me, not so much to fire at an apparition but in case I find a danger from THIS SIDE.
I have also had a recurring dream since I was a kid. being cut apart by dark, faceless figures. So disturbing and terrifying.
