Fix phantoms by adding nightmares back into the game.

Back in beta there was this feature where the player can have a nightmare. When a player sleep in a dark room there will be a chance for a zombie to spawn and wake them up. I think this feature should added back into the game but with a phantom instead. They will have a random chance of spawning when the player sleeps and will wake them up in the middle of the night. They will only spawn if there’s no roof above the players. head. Also, you don’t need to add this part. But after they spawn and when they’re gone. The player cannot sleep for a few days. On the topic of sleeping. I think beds should be nerfed slightly. And I also think there should be more reasons to explore the night. Before, you would need to go out to kill endermen for ender pearls. Villagers can trade them but it’s easier just to go out and kill endermen. But with the nether update. They can now spawn in warp forests. Another reason for exploring the night is for slime for slime balls. And for husks and strays for the monster hunting advancement. But they can now spawn in trial chambers. So please, add a new mob that spawns at night and not anywhere else or have mobs like the husk, stray and bogged drop a unique item. However the item can only be drop when they spawn naturally. Not from a trial spawner.
