When I was playing i heard a spider on peaceful! then a heard a door open, there was sopposed to be a stronghold near my spawn, but why did a door open and close? Also I heard a creeper go "sssssssssssssssss" then a person go "ooo a" but the wirdest thing is, I left the world and when I came back, my hole was not there that I dug. dun dun dunnnnnnnn.... Is herobrine back, or was there just a bunch of sound bugs?
