Quizplus · Accepted Answer

Nodding off during a class lecture suggests that the student is experiencing brief moments of sleep. These brief episodes of sleep are characteristic of Stage 1 sleep, which is the transition phase from wakefulness to sleep. Stage 1 sleep is often accompanied by muscle twitches and a feeling of falling, which could explain the head nods.
