Emag detacsufbo

I was finding a game that was my old favorite since 2012. I found it, but the name was different. Instead of the name "Minecraft", it was "emaGdetacsufbO.exe", I thought it was a hacked copy of the game. When I started the game, instead of Mojang logo, it was the glitched same logo. After that, the menu was fine. When I started the world, it was nothing but spawning a creepypasta called Herobrine.

It scared me, I checked the resource pack folders but there was no pack that has been added. He says repeatedly, "PolarHist, I will take your soul and be dead". After playing being scared with it, he still waits for me until the end of my life. REVE!
