Coma

A coma is like when someone falls asleep and can't wake up. If someone is in a coma, they cannot think, feel, or respond to what's happening around them. It's kind of like being in a very deep sleep. But sometimes, people in comas wake up after a few days or weeks. Comas can happen when somebody has a really bad illness or an accident that damages their brain.
