This dream was inspired by an episode of the television show The Punisher (Season 2) that I watched before going to sleep.
This dream is unclear but I know that it took place at a school, maybe high school and / or junior high school, and I remember the building probably only being one story.
My coworker Mr. CF was a security guard at the school, he was doing an undercover operation to stop a terrorist attack or some kind of attack at the school, and I somehow ended up going undercover to help him.
After a brief talk we went our separate ways inside the building, I was along a hallway near the entrance / exit hiding in a opening and / or room on the right side of it, and at some point I started sneaking around the school.
The people who were going to carry out the attack seemed to be members of a private security company / private military company, but I could be wrong.
I remember seeing and hearing some of them, they were either pretending to be handling security and / or something in the building or they really did have some kind of contract to work there, and so they were operating in the open because people either thought that they were supposed to be there or they really were supposed to be there which made things harder for Mr. CF and I.
We had to maybe avoid them so that is why we were sneaking around et cetera, but I can not remember what our plan was.
At some point I walked into a classroom where a class was taking place but some of the people we were there to stop were walking by the classroom, and so I had to hide on the floor by some students.
At least one of the students knew me and I tried to signal for that student and the other students nearby to not let the people walking by know that I was hiding.
The people stopped and they walked into the classroom asking if the class had seen two men, there was quiet, but then they replied no like I had signaled to them.
The men only did a quick look around and they missed me fortunately, and then they left.
Shortly after the class ended, an overweight male student with light-color skin approached me because he did not believe me, and he threatened to report me if I did not prove that I was telling him the truth.
He still did not believe me so I told him to call Mr. CF and he would tell him that I was telling the truth, I did not want to bother Mr. CF because he was probably sneaking around the building too, but it was the only way to get the student to believe me.
So I probably called Mr. CF and explained the situation, and I handed my mobile phone to the student so that he could talk to him.
They talked and then the student believed me, he gave me back my mobile phone, and I asked him to not tell anyone about this and why.
He agreed and then he left, but I woke up.
