If you are burned, your life is not smooth, and your cousin touches your wound, which shows that people close to you have brought you great pain. The blindness of college students shows that the attitude of your partners who study and work with you has changed, and you have tried your best to save your relationship, but the effect is very bad. Pressing the elevator button repeatedly shows that you are very uneasy and at a loss about your environment. Finding the elevator turned into a toilet shows that you are disappointed with the present environment. Not your ideal or favorite environment. Being laughed at when you meet a confession shows that you are embarrassed to get along with people around you. Peeing a little girl means that you are doing something you are not familiar with or good at.
These are just my views on your dream analysis.
Remember, in this world, even now, you are not the most unlucky, because in places you don't know, maybe near you, there are many people who are even more unlucky than you. Anyway, everything will pass, just bite the bullet.
