The Disappear Game

Have anyone experienced the disappear game? I don't want to be the only one, it's so creepy. This is the thing: That happened in march 6th, 2017 I was playing urf as karthus and i went jg karthus with smite. That was a relax and funny game before the creepy disconnection. I still remembered there were udry, wukong, janna and etc, i got a quad kill with an ulti xD and everyone was laughing. They were typing "xD" and "LOL" in all chat, and then after 30s I got my ulti ready again, i used it immediately when it was ready every time. Udry was crying and said "STOP KARTHUS", and after 10s the horrible thing happened. I was walking around mid and suddenly my screen turned into frozen, my ping went to 500ms and i was told disconnect to the game. I usually exit the game right after i saw the disconnection signal, i did the same thing this time. However, there was no reconnect button waiting for me this time, i just completely exit the game and back to home page. I felt weird about it and started another new game and hoping there was an error popping up to warn me "your are in a game already" but nothing happened, i just went in a new game!

I checked my match history right after the new game and there was no record about my urf karthus, but my last game was recorded correctly. I went to op.gg also to check my play history, same result, nothing about karthus. I just wanted to know where is my game, what about another 9 players in that game, did they experienced the same situation as i did? Or did i lose part of myself in that game? Where did i go?

IT'S SO DAMN CREEPY, I'M FEELING NERVES WHEN I WAS REMINDED OF THAT GAME.
