Kind of? I was in college walking on campus in broad daylight. I pass under this skywalk, with nobody in my general vicinity. As I do, I feel what feels like someone was walking past me coming from the opposite, locking their arm into mine. I got pulled back enough to stumble.
Sure enough, nobody nearby, no objects right near me or anything I could have accidentally gotten caught up on. Still have no idea what happened there. And for the record, this was before I ever had tried alcohol and I don’t really do drugs, so I can’t blame those.
