The Rainbow Apple

i was  playing some minecraft because i was bored so i crafted some wood to build a wooden house i made a wooden floor and a bed and i went to sleep when i woke up i saw a chest but i never built a chest but who cares i opened the chest just to see one thing something called A Rainbow Apple i ate the apple and then my character passed out then my character was in a dark hallway i only had the choice to walk to the end so i started walking but then i saw a black figure in the hallway i was scared the thing backed up and ran right at me i turned off minecraft never so scared before i told my parents about it but they didn't believe me and told me to go to bed i had a nightmare about the figure running at me with a knife if you ever see this in your inventory do not eat it
