Herobrine  signs                                                                                                                                                          I have play minecraft for a year now and I have seen some wierd stuctures in my worlds.This is one that everyone has had,your going mining then you run in to a cave unlike no other.A stone patteren on the walls all around you like a dome.HAs this ever happened  to you.The 2nd is that on the PE versoin I have always seen a mark on the ground.A cross,this is very strange to me.I don't trully know if this is a sign of minecraft you tell me.3rd and last,big trinch in the ground.Thats right, it's a reveane.People have different thoughts on this one,some say it's mean't to be in the world and some say its Herobrine.Once I was playing Xbox with a friend he left for a second and I sat and then his player was moving by its self I yeld his name and that it was moving.We thought we had got hacked but we did not it was HEROBRINE!!!!!!!!!!!!!!!!!!!!!!!!
