SIR, PLEASE TAKE IT SERIOUSLY

I was just playing a survival series then I came across a spruce forest by sea shore. The trees had no leaves and in the sea there was a sand structure. Then when I made a house and had gone for mining I dug into a cave. but the cave was ar Y: 22 and I saw diamonds when I had gone to mine them I was struck by lightning and died! When I respawned My house was burnt and I saw a steve like character. I thought it was a player but multiplayer was off and in the chat it didn't said anyone joined. I realised It was herobrine!!! He struck me by lightning!!! I hanged for a little bit. I was so scared I couldnt even take a screenshot and left the game and I delelted the world. He had no nametag and there was no mod and multiplayer was off!!

PLEASE DO SOMETHING ABOUT IT!!
