Ngl you should add some rare events that when you sleep you'll spawn in a world like your in a dream if you get what am going with. so like you will spawn in different worlds when you go to sleep but some will have puzzles and some with monsters to escape from the nightmare.
The game has a very creepy and almost "hacked" world creating fake messages and is unsettling to join, I recommend downloading this mod for sure for a horror experience. 👍 Also am thinking of using this mod in a short video, obviously giving credits to the creator and app, MCPEDL.
Add were you can respond to the fake player and allow the fake player to haunt the real player. It would add fun and also make the entity spawn more often
DONT FORGET TO TURN ON "Beta API"
