📋 About This Mod
**_MOD REQUIRES GECKOLIB!!!_** I personally recommend playing with golden days. Mod is best played in modpacks and not solo but thats just me lowk. Mods prettyyy slowburn... Welcome to Nightmares.jar, a minecraft mod heavily inspired by wonderland.jar (obviously)! This is a smaller mod that includes 2 new entities and 4 new dimensions, and is compatible with modpacks. I'd rather not get too much into the content here to keep it surprising, but be warned that it is horror based! But if you really need to know I'll include some of it down below, it'll just be spoilered. Big shoutout to ShatteredVines for some help with this! When you're ready, its time to dream. <details> <summary>Spoiler</summary> This mod contains 2 enemies so far, those being Him and Nightmare, Nightmare can appear in the overworld in later phases, but in earlier phases he only appears in one of the 4 dimensions. Each dimension can be entered through sleeping, and the more dimensions you enter, the more you unlock. Him can appear in any dimension, and just sends you back to where you last slept in the overworld, while nightmare does the same if you're in one of the nightmare dimensions, however if nightmare spawns in the overworld, they'll send you to a different dimension.
