Sleep Reworker transforms the vanilla sleeping experience into a fully immersive event — complete with animations, ambient effects, and a nightmare system that keeps you on your toes every night.

✨ Sleep Animation

When you lie down in a bed, the world doesn't just skip to morning. Instead:

A darkness effect simulates your eyes slowly closing
Floating "Zzz" text entities drift upward above you
Sleep particles cycle through phases (end rod, enchant, warped spore) throughout the night
Ambient sounds play as you drift off (harp and bell notes)

☀️ Normal Wake

Waking up from a peaceful night gives you:

A subtle night vision flash simulating eyes opening
A brief regeneration boost
Soft wake particles and a gentle sound

😱 Nightmare System

Every night there is a 25% chance of triggering a nightmare. If you're unlucky, you'll experience:

Darkness pulses and disturbing ambient sounds (phantom shrieks, cave echoes) throughout the night
Eerie particles — smoke, ash, crimson spore, soul fire flame — swirling around you while you sleep
On wake: blindness flash, nausea, slowness, and weakness hit you all at once
A dramatic "¡Pesadilla!" title fills your screen
And then… monsters spawn around you

4 Nightmare Types

Type	Chance	Monsters
👻 Phantoms	30%	3 "Shadow of the Night" phantoms circling overhead
🕷️ Spiders	30%	4 spiders + 1 cave spider surrounding you
💥 Creepers	20%	2 charged creepers + 1 normal creeper
🧟 Husks	20%	3 husks + 1 zombie reinforcement

All nightmare monsters have persistence — they won't despawn naturally, so deal with them.

⚙️ Configuration

To change the nightmare probability, edit one line in data/sleep_reworker/function/sleep/on_sleep.mcfunction:

execute if score @s sr_roll matches 1..25

Change 25 to any value from 1 to 100. Examples:

1..50 → 50% chance
1..10 → 10% chance
Remove the line entirely → nightmares disabled

🔌 GeyserMC / Bedrock Compatibility

The datapack is fully functional for Bedrock players via GeyserMC — all status effects, nightmare spawns, particles, and scoreboards work server-side. The only caveat: floating "Zzz" text entities use text_display entities which are not rendered by Bedrock clients. Everything else works perfectly cross-platform.
