I had a dream from when i was high school (ive been in college for a year) and i woke up crying??

Basically, i was on my way to my favourite lesson (not related much) and going through the business block when i saw a kid (maybe around year 7) and wondering why they weren't in lesson, cant remember what they said but i remember that i lead them to their lesson and telling them a stupid story when a teacher from a different subject came over (who is one of the nicest teachers i could imagine from what ive seen of her) and she starts yelling how SLT were looking for the kid and how they were supposed to be with them and how they thought they had left the school because they couldnt find them, and only found them because they could hear them laughing, and the teacher banned me from going to the business block??

Im really confused and woke up crying a bit ago
