I dreamed that my friend and I were killed.

Because your dream lacks realistic factors, I can only give you a general direction. I have three opinions myself. (1) You are in contact with these three friends in reality, but this process is not smooth and has been hindered to varying degrees. Strangers may be internal parents or teachers, but also the source of resistance in reality. As a unified group, students, you and your friends are facing great difficulties in their studies. That stranger should be the disguise of the school. (3) It shows that you and your friends have done something wrong recently. You feel guilty in reality, and then this emotion appears in the subconscious, that is, in the dream, so it is easy for strangers to understand.
