SimpleNightmares
by Kwember
SimpleNightmares changes what happens when players go to sleep, adding nightmares, ambushes and a sleep-percentage rule for skipping the night.
What it does
Sleeping in a bed can now trigger a set of events: a chance of a nightmare, a chance of an ambush, and wake-up messages. Nightmares apply temporary debuffs to the player. A player who tries to sleep in the open can also be ambushed. The night is skipped once a set percentage of players are asleep, so a server does not need everyone in bed to move on.
Hostile mobs that appear at night occasionally drop Lunar Fragments, a crafting material introduced by the mod, and the drop chance is low. The drop chance rises with the moon phase and peaks during the full moon. A Moon Lamp crafted from fragments and placed near a bed prevents nightmares, and the buff it grants is used in place of the debuff. Almost every chance and effect is set in a config file, so server owners can tune the balance to their own world.
Key features
Sleep events
Going to bed can trigger nightmares or ambushes, with a chance for each depending on the player's situation.
Percentage-based night skip
The night ends once a set share of players are asleep, which applies to multiplayer servers as well as single-player worlds.
Lunar Fragments
Hostile mobs drop a new crafting material at night, and the drop chance follows the moon phase.
Moon Lamp protection
Placing a crafted Moon Lamp near a bed prevents nightmares and grants a buff instead.
Configurable chances
A config file controls the chances and effects of nightmares, ambushes and drops for each mob.

Use cases
Who it’s for: Players who want sleep to carry risk, and server owners who want a configurable night-skip rule. The mod suits survival worlds and multiplayer servers on Forge for 1.12.2.
How it compares
Sleep Percentage is server-side only, under All rights reserved, and built for Forge 1.7.10, so it does not cover this version. Longer Day is open source under the MIT License for Forge 1.12.2, but only the server needs it, so players can join without installing anything. The Nightmare 000 is for 1.20.1 and runs on both client and server under All rights reserved.
