Let's talk about the mentality of those who sleep without turning off the lights.

Sleeping with the lights on is actually a mental illness that can't be ignored, and it is usually the main manifestation of fear. The pathological essence of sleep quality addiction with lights on is the fear of black glaze. In most cases, this fear of black scorpions is because children have just started watching or listening to too many horror stories, and the situation, content and characters of this short story often appear at night, gradually linking the fear of monsters with black scorpions. When they arrive at night, they are very worried. When they sleep at night, they are afraid to turn off the lights and rely heavily on them.

In addition, in the dark natural environment, I have suffered from terror, or was awakened by a nightmare in the dark. This fear can't be solved immediately, and it may also lead to the fear of darkness.
