Verified step by step guidance

Understand the context: Pieter experienced a sudden body jerk and a sensation of falling while asleep. This is a common occurrence during a specific stage of sleep.

Identify the phenomenon: The sensation of falling and the body jerk are known as 'hypnic jerks' or 'sleep starts.' These typically occur during the transition from wakefulness to sleep.

Review sleep stages: Sleep is divided into several stages, including N1 (light sleep), N2 (moderate sleep), N3 (deep sleep), and REM (rapid eye movement sleep).

Focus on N1 stage: Hypnic jerks are most commonly associated with the N1 stage of sleep, which is the lightest stage and occurs right after falling asleep.

Conclude the analysis: Given the description of Pieter's experience, it is most likely that he was in the N1 stage of sleep when he experienced the sensation of falling and the body jerk.
