Any sugestions for Weird unique dimensions?

I have some ideas:

-Realistic Dimension:  Very Hard/Insane Difficulty;  and as its name implies, it's more realistic, maybe even humans?

-Ultimate Dimension:  Nightmare Difficulty;  It is the heart of all dimensions, all the mobs are there, there are many biomes, and a final boss;  To access it, you need to visit all dimensions.

-Superform Dimension:  Normal/Hard Difficult;  It is somewhat like the overworld, but different;  there are a lot of big oceans on the surface, but there are many floating islands, it could have trading villagers, but more colorful, and generally, it's bright and colorful, it's colors are: Blue, Red, Green, and Purple.

what are the names of the dimensions you created?

The Deep Oceans

-Overworld generation but it is filled with water. Ground is generated as ores and there are a lot of strctures.

Here are a few random ideas:

• A Nether-like dimension that is made of ice, giant wither bones and dark wither trees. It should be mainly light-blue and black
• A huge and colourful crystal cave dimension
• An End-like dream/illusion dimension, where most materials are translucent or impalpable. It should mainly use cold colors and its sky should be black or dark blue/green
• A desert dimension... Except it's made of snow and ice. Snow pyramids, snow sphinxs and ice mummies could be found there
• An End-like dimension made of green toxic clouds where flying hostile robots can be found
• An End-like nightmare dimension where there are few flying islands and many huge monsters (dragons, demons...) that can apply many debuffs on you

I don't know how did I come up with these ideas, please don't ask

I also have many other ones, but those are for Hodge-Podge :P

Can I steal some of your ideas? XD

Because you just spoiled the second dimension of my mod alloy >:(

(Just kidding, I am not angry :D)

Of course, there's no copyright on them, they just were some random ideas I got while writing the list :P

it will be like advent of ascension?
