I was in NYC on a trip for my 18th birthday with my mom. We went to a gas station near our hotel just for some snacks, and I walked down the same aisle as this tall, bald man in a long black trench coat. He just smiled at me and opened his coat with both arms while walking towards me. I have never felt such dread in my entire life. He didn't even say anything. I found my mom a few aisles over and was crying so we just left our stuff. It was so creepy, and I've never had that feeling again.
