The Mediums

Introduction...
You can think that one letter names are cool. You can think they are a product of a hack. You can think anything, but I will never trust anyone who has a one letter name and nothing will ever make me forget these events.

Before...
Me and my friends were online now. We decided to go play some jailbreak. We played for a while until something weird happened. At exactly 12:12 A.M., a player named "m" joined the game. I thought it was cool that a player with a one letter name was cool so I started following him. He had a completely grey, blocky avatar. One of my friends continuously told me that it is impossible to have a one letter name, but that just made me more interested. After a while of following this guy around, he turned around and private chatted me.

"you are clean?"

"wat," I responded.

"you are." He said.

He started /e dancing at me. As soon as it turned to 12:13 A.M., the player left the game.

Story...
It was a few months later. By now I had tried searching up "m," but it wouldn't let me type in a username under 3 letters. Me and my friends were playing again, although this time we were filming a 3:00 A.M. challenge video. We were searching for Roblox myth games. After a few minutes of searching, I found a game called "medium hour." It didn't say it was created by anyone, which was weird. I asked my friends to play. They agreed and we all joined. I got into the game, but all of them said they were kicked because they "weren't clean enough." They moved on to a different game, but I stayed. It felt right to me. Just, peaceful.

The next day, I woke up at 12:11 A.M. I decided I should play some Roblox. I searched "Meep City" in the games page. Nothing showed up but that game medium hour. I decided to go play it. As soon as I joined, it turned to 12:12 A.M. 8 players joined at the exact same time, and they all had the same name, "m." There characters started coming out of the ground in a big circle. At the same time, they started /e dancing. I got scared and tried to leave the game but I couldn't exit the game no matter what I did. They all repeatedly said in chat, "We are the mediums. We are real. It is medium hour so we must spin the wheel." A wheel came up from the ground in the middle of all of them. It started spinning and in a few seconds stopped. they all stopped /e dancing and faced me. "We are the mediums. We are real. The wheel has spoken that you are the seal." It then turned 12:13 A.M. and they all disappeared. I was so happy that they were gone.

After...
From then on I kept on having voices in my head. All saying "We are the mediums. We are real. The wheel has spoken and we need the seal." I am paranoid of almost anything that would seem related to this. Help.
