The world feels supernatural at night, because nighttime opens up more possibilities for imagination. I think this is for three reasons.
You might be thinking less about work or daily practicalities. There’s more time for introspection. Even if you’re not tired, you’re also slipping more into a dreamlike state which allows for abstraction.
Another reason is that shadowy spaces naturally spark our imagination. Sometimes it’s in a fearful way, but fears can be creative.
Also, it’s because we can see the stars. This always feels like magic. Preexisting formations make us want to create; outer space absorbed into inner space. The galaxy reminds us of the seemingly endless expanse we can begin, bit by bit, to fill with ideas.
