Is it normal really weird dream?

Okay so the dream started off pretty normal, I was at a lake with these other people I don't know but apparently we were some sort of secret FBI team? We went into a building and killed some people then it turns out that my friend killed my other friend but didn't tell me so I got really upset and left.

Then I think the enemy team was in the area so I was hiding? I'm not sure I can't really remember but then I was held captive and forced to work for the enemy team, they beat me and one of them stabbed me in the shoulder with a knife (it felt like real life so I could literally feel how painful it was, I was screaming)

Then I get saved by my original team and the guy that killed my friend wants me to forgive him, idk what happened after that because I woke up. It was a really fucked up dream though and I've never had a dream like that.
