My pumped up kicks ahh dream

anyways so, maybe a couple months ago i had a dream, so i was in the cafeteria of my school during the day time when it was open like everyone right?
i was like talking and stuff to my classmates in the dream, then i got up and started walking to a exit out of the cafeteria, then i stood still after hearing something.

it was like THUD THUD THUD. i then looked at the other exit tables across from me, which was outside the cafeteria doors and was a glass double door leading to the outside.. THEN BAM! the glass shattered, I looked at the exit I was walking to but one of my classmates came up to me and started talking to me and i called out my friend name to follow me.
Then a other classmate started talking to me, i stood still. The gunshots were starting get louder during all of this, for some reason. when my other classmate talked to me i didnt run. I just stood there listening to him make his stupid jokes.

Then I woke up.
CAN YALL TELL ME WHAT THIS DREAM MEANS BRO :sob:
(also i wasnt trying to make a columbine joke, i lit study about columbine... maybe that why i had a school shooting dream.
RIP TO THE 13 PEOPLE WHO DIED IN THE SHOOTING ASLONG WITH ANOTHER PERSON EARLIER THIS YEAR.)
