Spooky Scary Spirit World!

Many people have been wanting Minecraft to get a new dimension for a while now and I believe it should be a spirit world! The dimension could be a dark waste land with dead trees and stones scattered about. There could also be mushrooms, mycelium, and even partially destroyed buildings. As for the mobs there are plenty of options. Phantoms could swarm the skies while a new mob (ghosts/spirits) float along the ground possibly being attracted to light or holding the new lantern blocks. Wisps would glow and lead the player either to loot or to there demise. Poltergeists could taunt the player and play tricks on them and banshees could scream to attack the player. Imagine how scary that would be! As for the Boss of this dimension the choice was a no-brainer. The Grim Reaper! It wouldn't be a very large boss, but a very eerie one. Using its giant scythe it would slash away at the player. When defeated it could drop it scythe and maybe some sort of rare new item. The scythe could be used as both a weapon and a tool able to quickly cut through plants (and maybe harvest more than usual).
