I live in Scotland, I think I've seen something we call the grey man. I love to go walking in the hills, it helps me clear my head, however just a few days ago when I was on may 2nd day of walking across the mountains, near fort William, I saw something that makes those quiet nights a little more tense. 10 miles south east of fort William, I heard a sound I thought was a plane at first however in hindsight, I think it was the grey man. when I was walking one of the main paths in the valley I was passing through I could see the sides of the hills, despite it being a foggy morning. I could see three boulders, then the middle boulder stood up, It was at least 6 meters tall, It must have seen me because it walked off, and with every stride I could feel every part of my adult skepticism fall apart. I got out of that valley as quick as possible, and when I set up for the night I heard that same sound, Whaling. This is not meant to be a creepypasta or any rubbish like that, I just needed to get this off of my chest.
