New creepypasta/backrooms level idea

I was at a water park a few weeks ago and i had an idea after i went down a pretty dark slide.

i just wanted to share and make a theory, if yall could add other things to it in the comments that would be awsome.

so here it is:

imagine if you went to a waterpark and found a slide out of order, but you were curious and decided to sneak to it in secret and go down the slide. what could go wrong? you start to slide down and everything goes super dark and the only thing you can hear is water splashing as you slide. 20 second passes and nothing happens. then 40. then a minute. then 2. you can feel something is wrong. this wasnt supposed to be a long slide. you still cant see anything because no ligth is seen. 5 minutes pass. you are alredy starting to panic. does this go on for infinity? it does. nothing ever happens. you are just sliding in darkness as oxygen starts to get low. and lower. you are paniking and you are trying to climb back up but it is impossible for some reason. your cries for help fades whit the darkness. and you can never get out.

i think it could be a good backrooms level. any ideas to add to it in the comments?
