When Zenyatta is recharging he makes a gentle humming sound and his orbs occasionally chime, so sharing a room with him is very soothing. When they first met it was like a lullaby for Genji. only the first time he tried to sleep on his master’s lap zenyatta started to float mid-recharge and he fell off :( I also like to HC that he tends to pick up on the dreams of those sleeping around him.
