Gaster showed up as an evil force in my dreams I had to escape from again. I kind of feel bad because he's done nothing but be helpful by making the core, connecting me to Deltarune, letting me make a vessel, telling me the release date of Chapter 5 and helping with the Knight. The dream was fun, though. I had descended into some area and had to return through the (Ch4-inspired) areas I've visited to escape from the looming threat with the help of a wiki article, there was something like a quiz where I had to decide who to give the "white mantle" to, not the sky mantle but an item that would choose who the girl would be, and at the end I turned into a bear before reaching Heaven.
The attached picture isn't very accurate, I just felt like I should make something to accompany the wall of text, even if it's a shape tool mess because my pen still doesn't fucking work.
