the Dark Kingdom is real, but those aren’t our heroes “normal” bodies. Kris and Susie have different clothes, different belongings, and even different SKIN COLOR there, and on replay, you can reach the dark kingdom by sleeping. Does this mean it’s all imaginary? no. it’s a real, physical place, that has physical bodies kris and susie take control of when they fall asleep.
thinking bout how it’s an oddly consistent them in deltarune that the four main characters of the game - kris, susie, ralsei, and lancer - all either have no visible eyes for a majority of the game or constantly have their faces covered. lancer’s got his spade hood/mask(?), ralsei’s face is shrouded in darkness by his hat, and both susie and kris almost always have their hair covering their eyes.
hiding the face is often a literary tool to indicate someone is hiding something. Susie was hiding her self doubt and anxieties which cause her to lash out in anger
Lancer was hiding that he knew his dad wouldnt let them go
ralsei was was hiding their true nature of who they were
and kris was hiding whatever the fuck that ending was
