Can't Sleep
by cintreck
Can't Sleep adds unlucky nights on which a bed refuses the player, who must stay awake until morning.
What it does
On a given night a bed use can be rejected by insomnia. The chance defaults to 15 percent of nights, and when it hits, the sleeping player stays awake and has to wait for the morning. Other nights show a message that similar monsters are nearby, and sleep is blocked until the next day. The sleepless nights follow the world seed and the day, so every player in a world gets the same sleepless experience on the same night.
The mod requires Fabric API and runs on any Fabric setup. The server enforces the rules, so the server needs it, while players may add it only for optional interface tweaks. Cloth Config API and Mod Menu are optional, and when both are present they expose the settings in-game through a config screen. The code is open source under the CC0 1.0 Universal license, and files are published for Fabric across 1.21.2 – 1.21.10.
Key features
Unlucky sleep nights
On some nights an attempt to use a bed is rejected, and the player stays awake until morning.
Shared sleepless days
Sleepless nights are derived from the world seed and the day, so the whole server shares the same schedule.
Monster warning nights
On other nights a message reports similar monsters nearby, and sleep is blocked until the next day.
Configurable chance
The percentage of sleepless nights can be changed, with 15 percent as the default, through the config screen.

Use cases
Survival servers
Server owners who want sleep to carry some risk can run the mod on the server, and players join without installing it.
Shared hardcore-style worlds
Because the schedule depends on the world seed, a group of players on the same world meets the same sleepless nights.
Who it’s for: Server owners and players who want beds to be less reliable on some nights. Clients only need the mod to adjust the interface.
How it compares
Day Bed is a client and server mod with CC0 1.0 Universal licensing that is open source, published for 1.21.11. RealisticSleep is also client and server, under the MIT License, for 1.21.1, and is not open source. AudibleDayNight is client-side only, for 1.21.11, and not open source, so it changes nothing on the server side.
