Can you use your Familiar to wake another creature that is affected by the Sleep spell? Or the Eyebite spell? It seems like an extremely powerful use of an already overpowered Spell, negating a 6th-level spell.
Find Familiar states:
Your familiar acts independently of you, but it always obeys your commands. In combat, it rolls its own initiative and acts on its own turn. A familiar can't attack, but it can take other actions as normal.
And Sleep states:
each creature affected by this spell falls unconscious until the spell ends, the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake.
Asleep. The target falls unconscious. It wakes up if it takes any damage or if another creature uses its action to shake the sleeper awake.
