I dreamt intermittently that my deskmate was a student for 5-6 years. Somebody help me, I'm going crazy. She is my deskmate in junior high school and a classmate in senior high school.

Dreams are actually a reflection of the inner subconscious, which may not be noticed in daily life. Maybe you like him (her), or you bully him and feel guilty? Anyway, you can contact him. After all, after a class meeting, catching up with the past may untie some knots and won't have nightmares. I hope to adopt.
