Great theory, and I agree with you! Possibly Gaster works in the underground lair (underneath the school where if you speed up the music it's Gaster's theme, supposedly), and is experimenting with time and space there. Also, maybe, Gaster managed to get into the area that Susie and Kris fell down, and thats why there're references and such down in the underworld there.

Anyway, great theory, and have a happy holiday!
