This is what happened to me :
i was on MC multiplayer on a server called melonCraft i was mining some coal behind a lava lake and i used some cobble to fence the lava out then when i looked back the cobble was breaking !!! luckily i didnt die i looked around in horror no one was there !!! Then i knew it was HEROBRINE I then closed up the cave i left a sign for my friend explaining the story and he left a sign saying: im coming in,THAT MO'FUCKERS GONNA DIE FOR HURTING YOU !!! I never saw him again on that server ( He probobly got freaked out and left )
