The sleep cycle: a naturally fragile moment
To understand these awakenings, we must first examine the mechanics of sleep. The night is divided into 90- to 120-minute cycles alternating between light sleep, deep sleep, and REM sleep. At the beginning of the night, the body prioritizes physical recovery through deep sleep.

A faint noise, a movement from a partner, a change in temperature, or an internal bodily signal can be enough to trigger awakening.
So you're not dreaming: these hours correspond to a biological window where sleep is precarious.
