Duke Zhou, I dreamed that my brother was riding an electric car.

Pay attention to the possibility that others will speak ill of you behind your back. But you should also be careful what you say and do. Especially when talking about topics related to bosses and teachers, be careful not to be too explicit, so as not to let people report. Also pay attention to talking to the teacher, and don't talk back with boring arguments. Maybe you are joking, but it may not be the case in the other person's ear.
