It’s a funny thing actually. So, you are starting to fall asleep; your brain starts sending signals throught your body to prepare you to sleep. Your heartrate slows down, your breathing slows down, your body temperature starts decreasing. Your metabolism slows down. Sometimes, the same brain that sent signals to make these asjustments thinks “OH SHIT WE’RE DYING” and so sends a jolt of signals to wake you up.
