I have found (or rather found me) the legendary Herobrine. At least, I think that's what I saw. I was building my house in singleplayer in peaceful mode, and had just started playing this world. It was in the forest, and things were lagging pretty terribly. I set my render distance to tiny, and that fixed the problem pretty quickly. Though, I had seen no animals around, which was strange, but I ignored it. I turned around to gather more wood, and jumped out of my seat. To the right of my screen I saw an obviously huminoid mob. The figure was completely black, or at least it seemed, because a split second is all I had to spectate before it vanished as soon as it came. The sound it had made when it appeared was similar to the sounds taunting the player in a cave, only very much more exaggerated. I immediately exited the game and looked into the minecraft file to see if the Herobrine mod was still in use. Nothing. I had deleted that mod months ago, along with all other mods I had used. Does anyone know what I saw? I'm a strict believer in Herobrine, but I hate made up stories, and I promise this is not one of them. Please reply or message me if you have had a similar experience yourself.
