So i dont know if this is a glitch or if it has happened to alot of people.But anyways it is really creepy.So i will be just playing minecraft and ill be walking when (im not sure if my ears are playing tricks on me)I will be walking and i will hear this weird mettallic sound.Like as if someone is playing creepy music but no one else will be in my game because its in singleplayer.I will also start a new world and i will hear a nether portal out of nowhere and i know it cant be a stronghold portal because it was on superflat.It is as if someone else was already in my world...
Has this happened to you?
