A member asked:

I bit the tip of my tongue hard and was bleeding as i was falling into a deep sleep, what could of caused this?

A doctor has provided 1 answer

Hypnic jerk: This hypnic jerk is a normal part of falling asleep. Your body is transitioning between wakefulness and sleep as control changes between different parts of your brain. As for your tongue injury it will heal very quickly, about a day. It is amazing how quickly the mouth and tongue can heal.
