My brain is already trying to convince me that it was just my imagination, but I was standing on the train platform and had a creepy feeling like someone was going to try and push me onto the tracks. I started leaning back away from the tracks involuntarily, and as the train arrived, in the reflection in the train windows, I saw a man with both hands raised behind me as if getting ready to push me, but his head was lowered, hanging down.
I have never seen a ghost before. I saw a great big black shape once in my apartment in Kyoto, in the house that was over 100 years old. I think that was a ghost, but it was just a big black shape. This was literally a recognizable person.
