yes
save wrong warps and normal wrong warps are different things. normal wrong warps are performed by backing out of a screen transition frame perfectly while holding x/shift and c/ctrl, which then puts you at the default point of the room you're entering rather than the entrance you're coming from. you can perform them while you have wrong warp state (which you have after loading a save or after certain cutscenes like the one in trash zone), they are possible on every version of the game, and they are allowed in glitched and nmg categories. save wrong warping is a 1.09-exclusive glitch where, as a result of a coding oversight, dying/reloading a save in certain rooms will teleport you forward 1 room, which can be used to do things like skip the hathy in field by loading the save in that room in chapter 1 or skip giga queen by dying to her in chapter 2. this is banned in the main glitched categories, and is only allowed in the 1.09 categories that are in misc. (and also on CE glitched categories but that's a different thing lol)
you have to have a completion file in your deltarune saves folder (normally at C:\Users(your username)\AppData\Local\DELTARUNE on windows) in order to do bed skip; the saves that you can download in the resources tab include completion files if you want (they're named filech2_3)
