in the dream, i was playing this mario 64 romhack (been nicknaming it 'skeleton mario' for obvious reasons) where it starts with mario getting a letter from luigi, telling him that he's been taken by ghosts and mario needs to come save him

the romhack then played out like the regular mario 64 game, with only one difference: you had the poltergust, and you'd randomly run into ghosts and have to take care of them before continuing. if you had five or more ghosts in your vincinity, the edges of the screen would darken, and a warning indicator would appear at the top of the screen (not sure if it was due to dream stuff or glitching, but i couldn't read what the text said- just that it was in that colorful blocky mario 64 font)

if you didn't take care of the ghosts in time, a timer would start counting down and skeleton mario (black and white faceless mario with a 2d png of a poorly drawn skull floating in front of his face) would run towards you. whenever he touched mario, the game crashed, a bunch of generic creepypasta images would pop up on your computer, and it would copy a bunch of spooky symbols (pentagrams, zalgo text, etc) to your clipboard
