This happened a few years back, I can't remember the exact year (2005-2006). My friends and I were fishing freaks; we went fishing every weekend as much as we could. Now we've gone to this particular area in Elk River, MN many times. The fishing area is under a small bridge for a single lane road, the river ends at a dam or concrete wall right under it passes the bridge.
To get to this site, you had to park behind a small business building and walk a wooded area down to the river, maybe 45 feet down. There's a little path made from people walking the same line down to the river, but to the right is tall grass about 2-3 feet high which stretches 3-4 feet into a wooded area. There's also a train track very nearby although we've never seen it, we know its there.
This particular night, we decided to go night fishing there. We've done this a few times before and were comfortable with the area. There were about 12-14 of us couples. For some weird reason, as soon as we got there, I had this huge uneasy feeling as if being watched or as if something was going to jump out at me. Despite my feelings of uneasiness, I decided it must just be me and my imagination, plus I'm afraid of the dark.
We built our fire and started fishing. We were there for a few minutes and I had to run back to the car for something. I forced my two friends to go with me. As I follow behind them through the tall grass, I can sense someone/something in the grass watching us. I was creeped out but didn't want to mention anything since my friends are believer of the supernatural too.
We got what we needed from the car and headed back. After a few minutes or half an hour, a train came by. All the times we've been there, we've never heard the train. As it came flying by, we can hear something falling off the train and rolling down the ditch to where we were along with a cry... This was not that of a person.
My guy friend and I fishing next to each other just looked at each other asking if anyone had heard it. No one said anything. A few moments later the tall bushes behind our fire started shaking hysterically as if it was windy. My friend sat in front of the bush and didn't feel any wind, no one else felt any wind, and it was a calm summer night. I was under the bridge fishing when I looked over and saw the bush. It wasn't swaying as if it was windy, it shook as if someone was under it and grabbed the bush and shook it with their bare hands.
This was the final straw. There was a group of people night fishing across the river from us too. But we couldn't stand to stay there no more. Finally my friends said "let's go to the store". We forced everyone to "go to the store". In my culture, it's believed if you experience anything or even if going home from an event, you don't say you're going home, in case something follows you home.
So we quickly packed up and left. We didn't want to go straight home in case it had followed one of us, so we headed to the store. Talking with my friends, they told me they had the eerie feeling as soon as we got there too. I wasn't the only one.
I don't know what it was, but it sure wasn't a ghost. It's more likely some kind of demon. Let me say, that was the last of night fishing for us!
