you where board (not in the Minecraft world yet) so you decide that you where going to play mine craft... You grabbed your computer (or what ever you play on) and started up Minecraft when you entered your world you felt uneasy... You keep playing mine craft for a few more hours and then you thought you heard foot steps of a player you logged off and closed your computer (or whatever) and stayed off it for the rest if the day (charters: Herobrine and you)
