I have very heavy nyctophobia when I'm alone in a room, which makes sleeping without at least a desk light on difficult.
But of course the desk light makes me sleep poorly so I wake up more readily with it on.
Catch-22.
@Moa Low intensity ambient lighting usually helps tremendously. Stuff that casts onto the wall. Cheap LED strips mounted on the back of furniture works wonders on keeping the room visible but cozy and non-wakeful.
@esdin I'll have to look into this!
