Herobrine on Pocket Edition

So, I was all alone at my house. My dad was at work and my mom went to shopping in a food store just next to our house. I was bored and I wanted to play MCPE Survival. I spawned on top of a tree for some reason. I thought that it was just a bug. So I got off the tree and collected some wood. While I was doing that I heard some flint and steel sounds. I turned around and the tree I spawned on it's top was on fire! I tried to stop the fire but then I got in fire without even touching the fire. I re-spawned, but this time near Herobrine. I exited the game no matter what and deleted the world.
