A mod that adds various sleep events to the game, including nightmares, vicious ambushes and the ability to set a sleep percentage/player amount to skip the night even if not all players are sleeping!

This mod adds:

The ability to set the percentage or amount of players that need to sleep to skip the night on servers. Now including wake up messages!
A chance for the player to have a nightmare when sleeping. Nightmares give the player temporary debuffs.
A chance for the player to get ambushed when trying to sleep. Dont sleep in the open!
A new crafting material, Lunar Fragments. These are dropped by hostile mobs at night with a low chance. The drop chance scales with the moon phase, the chance is highest during a full moon!
A Moon Lamp that the player can craft with these fragments and place near their bed to prevent nightmares and get a buff instead

A lot of this mod is controlled in the config file! Please take a look in the config file of the mod when trying it out, as a lot of chances, effects and mobs are arbitrarily chosen as an example!
