The expression "doze off" means to fall asleep unintentionally or to start falling asleep. It's used in informal settings and can happen when you're sitting down, such as in class or on a couch. For example, if you feel yourself starting to become sleepy while sitting in class, you might say "I'm about to doze off" to let your classmates know you may not be fully alert. It can also be used to describe someone who has already fallen asleep unintentionally.
