Okay, what's going on around here?
Admittedly, I'm not an interior designer nor have I learned anything about architecture. But with my minimum knowledge of playing the life-simulation game The Sims 4, I am very sure that these stairs cannot legit exist simply because they are life-threatening. It takes a lot to fail on something that is so inherently basic and proceeds to try to be different but ended up with the most confusing and dangerous part of the building/house.
Brighthumanity happened upon a lot of stair design fails, unfortunately, but be warned that these might just give you the anxiety you didn't need. Otherwise, have fun!

#17 This isn't a staircase, but a waterfall. Of course, someone mistaken it and slipped on the 'stair'.
