The idea
Stage N1 is the transition into sleep, marked by slowed brain waves and easy awakening.
In practice
A person nodding off in a chair jerks awake and insists they were not asleep.
Where people slip
The sense of not having slept is common in N1. Subjective report and recorded stage separate here.
