As we all know, sleeping is an exercise to make the body recover after a hard, exhausting day; it helps the body and brain heal, regenerate, and reenergize. If you don't get enough sleep, you might suffer side effects, including poor memory and concentration, decreased immunity, and mood swings.
Several people sleep in a dark and silent bed. The rest with a bit of lamp on that don't mind noise. However, I like sleeping in a dim and quiet room because it can be hard to fall asleep with the lights on and the noisy noises. If we cannot rest, it ensures our body cannot recover the whole long night because when the next day arrives, we will have absolutely no stamina and be wholly drained the entire day. We can't sit up to do our job and homework on that day, and that's not what we all expected.
In that way, I would prefer to sleep in the dark and quiet. You might find it frightening in the darkness, but you can get used to it in a few days because there is nothing to be scared of.
