Tired. But still wide awake.

When I was 33, in autumn 2019, I sat on the edge of a bed in a sublet in Cologne at quarter past midnight. My legs felt like they belonged to someone heavier. My eyes hurt from being open. And my brain was running a slideshow of every small thing from the day: a tone in a Slack message, a stranger on the tram, the way the cashier had looked past me. I was so tired I could have cried. I could not sleep.

If that is roughly the shape of your nights right now, your reaction is not a malfunction. A sensitive system takes in more during the day, not less. More tone, more facial micro-shifts, more background noise, more emotional weather from the people around you. By 11pm, your body has spent its budget and is ready to lie down. The processing queue, however, is still working through the day's input. Two different parts of you, two different clocks.

Here is the one-sentence label I want you to take from this lesson, because it changes how you treat the night: My body wants to sleep. The system is still online. That is the real pattern. It is not stress in the dramatic sense. It is unfinished sensory and emotional processing, running in the background while you stare at the ceiling.

Try this for thirty seconds, right now while you are reading. Put both feet flat on the floor. Let your shoulders fall about a centimetre. Exhale once, slowly, longer on the way out than the way in. Notice that your body responds almost immediately, even though your thoughts keep going. That gap, between a body that can settle and a mind that keeps chewing, is the thing this whole course is built around.

Most sleep advice ignores this. Scroll until you crash, pour a glass of wine, put on a series. For a less sensitive system that might work. For yours it adds more input to a queue that is already full. (Honestly, I lost years to that mistake before I worked it out.) The course gives you three steps instead, by name: Settle, Park, Close. Settle lowers one input. Park gets tomorrow out of your head and onto paper. Close gives the body a physical signal that the day is done. Soft Ohropax, a Decathlon sleep mask, the small desk fan I keep running, those are tools that serve Settle. They are not the cure. The sequence is.

So tonight, before anything else, just notice which one you are: a body that is tired, or a system that is still online. Both are real. They need different things.
