Entity 234

Once I had just joined My Minecraft server on MCPE it was normal as always, I said hi to all the players, but then when I joined Bedwars, there was only 1 player, but it said there was 666/25 players online and that player then looked at me, the sky went dark, all I could see was That Player, no name, and had a slightly transparent skin, with a dark red robe, and one of it's shoes was longer than the other and it wore a degraded belt, with one singular red eye, after I had analyzed his player skin my screen went entirely black and then I heard crying, and laughter overlapping each other, and when it was done, My door knocked, I opened the door and nobody was there, when I had turned around everything went black, I blinked and then everything was normal as it was, but something felt off, I ignored it and went to bed, the next morning my mailman knocked on the door, to give me my mail, and then he said to me kind of stuttering, "Did you see that robed guy by your house just a second ago, he left a letter under your bush." I then looked wide eyed at him, "H-h-how did you know it was a he?" after I had said that my mailman booked it. Thanks for reading! Stay tuned for part 2! :)
