I dreamed that I was locked in a room at school, unable to contact with the outside, slept all night, and was rescued by a primary school classmate the next morning.

Tell you positively: dreams have a lot to do with reality, but they are two different things. When the human body goes to sleep, not all cerebellum and brain stop discharging, because some cells will continue to discharge, arouse memory nerves, and make people dream about real and unreal situations. Our ancestors also said: the sun thinks and dreams. Don't worry about anything, just live a confident life again.
