To be clear, I have made this with MCreator, some people will hate me for that, but who actually cares.

This is my first ever minecraft mod, the music is from Toby Fox

Music rights administered by Materia Music Publishing.

This mod allows you to hold the Somnium firework to gain altitude towards the sky, after 4ish seconds you will teleport to a new dimension with a custom biome.

To teleport back you must sleep on a bed.

Inventories are separate from dimensions

As of mod version 1.3.0, Somnium will no longer support 1.21.8 and instead support 1.21.1, you can still download and experience the mod for 1.21.8 with versions 1.0.0, 1.1.0 and 1.2.0
