Why is Rest a Psychic-Type move?

Question

I mean, Pych Up isn’t even a Psychic-Type move (it’a Normal-Type), so why should Rest be?

GF logic

Meditation, Maybe?

Could someone tell me why Psych Up isn’t a Psychic-Type move, too?

Again, GF logic

Girlfreind logic!?

Answer 1

Possibly because the Rest definition is that the user falls asleep, which could be associated with Hypnotising itself into sleep, healing all its status.

Answer 2

Although no one outside of GameFreak can say for certain, one reason Rest could be a Psychic-Type move is because it makes the user fall asleep, allowing it to rest it's brain (with psychic power often being associated with the brain).

Hope I helped :)
