It depends on the situation to sleep alone in the university dormitory. The whole dormitory should be quiet. If it's very late, for example, it's past 23 o'clock in the evening and someone in the dormitory wants to rest, then other roommates should be considerate even if they are not sleepy, consciously lower their voices and remain silent. If it is broad daylight, everyone is busy with their own affairs, and some people want to sleep and rest, so they can ignore it. The dormitory is not her own. If she goes to bed at an inappropriate time, will others waste time doing nothing until she wakes up? It is normal to have a little friction in collective life, but as long as everyone puts themselves in others' shoes, I believe that the dormitory life will be very happy in the future.
Try to synchronize your sleep time with others. When sleeping, some small sounds will be infinitely amplified, even making it difficult to sleep. Then this person's mood will become extremely bad and his attitude towards his roommate will be very bad. But in fact, I have tried to keep quiet for my roommates, but some voices are inevitable. So you should adjust your schedule so that you won't have this problem when you sleep at about the same time.
I wish you a happy college life.
