Question

Quizplus · Accepted Answer

The hypnagogic state, characterized by vivid sensory phenomena and the feeling of beginning to dream, actually occurs during the transition from wakefulness to sleep, not in the deeper stages of sleep such as Stage 3 or 4. Stage 3 and 4 are characterized by slow-wave sleep, which is the deepest sleep phase and not associated with the hypnagogic state.
