The world at night is not the same world as the world in the day.
The physics is the same. The geography. But the experience of it — what it does to you — is different.
At night, the prefrontal cortex — the planning, analysing part of your brain — goes quiet first. This is why night thoughts feel different. They're less filtered. More honest. More frightening, sometimes. More creative, often.
The body begins to lower its temperature. The pineal gland releases melatonin. The heartbeat slows. Breathing deepens.
You are, without deciding to, becoming something slightly different.
Animals know this. The diurnal creatures are settling — birds in their roosts, butterflies on their stems. The nocturnal ones are waking. The world is handing its custody from one set of creatures to another, as it has done every day for four hundred million years.
The stars you can see tonight are the same stars sailors navigated by, the same stars ancient humans named and made into stories, the same stars that were here before the first human eye ever looked at them.
The dark is old. The dark is not dangerous. The dark is simply the other side of something you've been doing all your life.
You've woken from every night you've ever slept.
You will wake from this one too.
Everything is in order.
Goodnight.
