I don’t like to sleep in near pitch black rooms. It just feels unnatural to me. It may be more the fact that it prevents the gradual transition to daylight unless you’re using an artificial light, so that bothers me more because you don’t know when morning is. But even when traveling I love to keep the curtains open through the night and sleep to whatever the natural light level is around me even if it’s in the middle of a city.
I wish I had your superpower. I need the room pretty dark to sleep well.
Doesn’t have to be total darkness. I like there to be a small amount of light. My bed has underlighting, so you can see the floor. But it’s not blasting you in the eyes. Works pretty well.
I really dislike sunlight creeping in through the windows in the morning. My shades block 98% of it. But the windows face south, so sunlight leaks in around the edges. They make edge seals for this, but I haven’t tried them.
Once I’m awake, I do like to throw the shades up. Sunlight is better than artificial light when I’m up and about.
