So I've been playing the game for a while now, and i've noticed a glitch in the game which is super creepy. In creative mode I start flying over land and some of the land doesn't load immediatley so i see a binch of weird rocky pathways underneath and sometimes even floating rooms and mobs. But when i fall to maybe enter this under world, the land appears underneath and the under world goes away. I tried digging to see if i could reach it (stupid idea) but obviously all I manage to reach is the Void. What is this underworld and can you get to it? If yes how? See the pic below
Thanks for your help and yes, I'm a girl, i play minecraft. 
How to get to the minecraft underworlds?

Load generating error, it happens the pathways underneath are just caves. If you leave the area and come back it should be gone

Yeah it's just the game rendering, those weird rooms you can see are just caves you can dig down to them if you wanted.it's just the chunks loading

This isn't a glitch. The world just can't load fast enough when you fly around in Creative. This is only a visual issue. Pressing F3 + A will reload the chunks. The pathways and rooms you see are caves and dungeons. If you want to go there, just go digging underground.
