What are the not-to-do things at night?

السلام عليكم ورحمة الله وبركاته brothers and sisters

As the title says I've heard from my parents and brothers about things not to do at night like looking at mirrors for too long, keeping windows open Etc and I want to know exactly what not to do at night because I'm a little paranoid and ya so please provide me a list of things that were mentioned in hadith or the Quran that I shouldn't do at night thank you
