When I'm alone at night, I sometimes hear other people's laughter-_-

If there are no other people or residents next to you, then hysteria is more likely. My first love was hysteria. At night, I often see people or other abnormal things enter her room inexplicably, and I feel very scared. It is for this reason that my family is firmly opposed to my association with her. Later, we broke up. I've been with her for more than three years. It's beautiful. I still often recall the days with her. Okay, okay, let's not talk about it. This is beside the point. What I want to say is, if it's hysteria, see a doctor quickly. I wish you a speedy recovery!
