What is the meaning in a dream of high school

I dreamed of a high school crush and I was having an affair and his wife found out and left him.

Last night I had a dream where me and my friends were outside at highschool with lingen, but the high school wasn’t Lincoln, it was St. Bernards. Then we started to hear shots, so Mr. Lingen was trying to find a way out on school grounds. He found the CAP van but it was red and had like 10 seats. He was hoping the keys were in the van and I found them so we all hoped in but there weren't enough seats so kendal sat on my lap. We drove across the street but it was at Daniella's house and she doesn't live over there. We got there and sat around for a while then the shooter found out we were there so he started to try to come inside and when the door opened I woke up.

I dreamt that i was having dinner at a friend house who was married to one of my friend husband, but they were getting a divorce. Then I ended up at my old hr high school. With my security guy who I work with. I seen a baby kitten in the snow. All of sudden a Bob Cat appear in front of me with huge tucks, I called out for help to my security guy not to leave then the bob cat jumped in front of me, then I woke up.
