I understand you, I also like to sleep in the dark. That is why even a small amount of light interferes with my sleep, it will affect my sleep. I know too well that sleeping in the dark also results to better sleep virtually for everyone.I definitely don't mate. If I was still a kid, it would be completely a different thing and also understandable for me to be afraid of the dark because our parents even made it possible for us to fear the dark.
