You bolt awake in the dark, heart unsteady, mind suddenly loud. The clock says 3:27 AM—again. Why this hour? Why this pattern? And why does it feel worse every night?

The pattern isn’t a mystery or a curse. It’s a message. Listening to it—and adjusting your habits or seeking medical help—can turn 3 AM from a battle into peaceful, uninterrupted sleep.
