what does it mean to dream seeing someone i dont know get shot?

i dreamt like i witnessed a frat war near school. i find it weird cos im not even associated or friends with any of the fraternities in school.

i dreamt i was inside my parked car near school, then i saw someone got shot point blank near my car. i screamed then the gunman & his companion from frat B heard it then looked at the windows of my tinted car. me & my friend were so scared. they didnt see us so they went to their car which was parked right beside my car. my friend immediately went to the driver's seat and drove my car. which was weird cos i remember telling her not to leave the place right away cos then the killer might know that someone witnessed what happened. but then when our car left, the car of the gunman didnt follow us. gunman might be from frat B

fast forward a few hours, still terrified with what happened, i was in this condo right in front of my schol and i was in the company of frat A. i dont remember telling them that i saw the shooting incident but i had this feeling that they knew that i was there. then police came asking frat A if they had anything to do with the incident. the police showed a list of car plates and my car plate was on the list although some of the letters/digits were wrong but i knew it was my plate.

what does this dream mean? weirddd.
