Untitled Sighting

Hello, My fiancé and I were out fishing on the Pete Marquette River just off of Walhalla Rd. Off of US 10 just west of Baldwin MI.The incident took place at around 1am in the last week of June. I was standing in the river fishing for trout during the Hex hatch. When In the brush in front of me I heard some unexplainable sounds. It sounded like mumbled talking and it was not human like. It scared me so bad. We got out of there. Earlier that night we heard some screams off In the distance, noises that we had never heard before. I did not see anything. I told one person about it, a fellow angler and he had an encounter in the same exact area. He saw the creature in the moon light and said it followed him all the way back to his car. He also told me I am the 3rd person to tell him almost the exact same thing. There is something out there worth investigating.
