[ELI5] Why does the tongue rest on the top pallette of our mouths while we sleep?

Answer 1

The tongue is a muscle, and like all muscles, it gets tired. When we sleep, our muscles relax, and the tongue falls back into the mouth. The tongue rests on the top palette because that is the lowest point in the mouth.
