Its not Gojover yet!
I expect this to be because of Shoko wizardry or something similar. People being sent to her right after they get near death or die seemed like a Chekhov's gun.
It can also just be Yuta with 6 eye implanted into him, and would explain why Gojo's "ghost" is there, because Yuta would've taken his eyes and copied limitless.
Its gotta be one of these two, I dont think Sukuna is near death and hallucinating.
