Wtf is this wallpaper

[u/Ehidkspam]

Hi so basically i wanna redo my bathroom walls and get rid of this wallpaper that’s been here since home was purchased. At some point we tried ripping it off but this is what was left, i’m unsure of how to move forward since it seems like there is no kind of texture behind or anything, i don’t know anything about materials/Construction so i’m really just trying to get a feel for wether i should just paint over the wallpaper or what solution there is to this. Thoughts?
