not really no, the light sources in my room come from the light in the hallway from under and over my door and / or my bathroom since the bathroom is connected to my room. If those both happen to be off, the air conditioning unit in my window emits it's own blue light
Hell nah, I used to sleep with a night light when I was younger, but suddenly one day I just couldn't stand light in my bedroom anymore. Now I can't sleep if there is even a tiny light source in my room.
When I was maybe 5 was terrified of the dark! Would always imagine being chased on steps with the darkness behind me. I want to say this came from watching "scary" movies early on, but I'm not sure. I think at some point, the night light burnt out and I never went back to it. Worked out in the end! Now I need absolute dark in the room otherwise I've some trouble falling asleep haha.
I sometimes sleep with a light on. I used to need to sleep with all the lights on because I was so anxious in the dark. But I'm happy to say I've mostly gotten over that and most of the time I feel fine in a completely dark room!
