you start to enter the supposedly cursed forest everyone says it is, its the quickest way to your friends house for the halloween party so you enter in your costume, suddenly you see a glowing tombstone in front of you that says "Dream", you approach it and Dream appears behind you with his book, ready to turn you into a monster based off your costume, some of the monsters include Tommy (demon), Tubbo (bee man), Wilbur (ghost) (This AU belongs to Grimmijaggers on Youtube)
