gee theoretically sollux could have had a god tier AND a dream self at the same time couldn’t he? or would all three bodies merge? also... what would happen to the “irl” body if a dream self went god tier while the player was sleeping? would they still merge even if the meat body isn’t on a quest bed?

It’s hard to tell, God Tier seems to be a Dreamself-Realself merger so like… The other Dream Self may also just die. I assume you mean if the Dreamself went God Tier on the Sacrificial Slab in Prospit/Derse, because otherwise the IRL body needs to be on the Quest Bed to ascend. But no idea? The closest we’ve seen is… Like… Aradiabot blowing up when she God Tiered. So maybe your Real Self would kind of. Die nontheless? No idea.
