Is it normal to dream about being forced to kill your friends?!

So I'm not going to go into huge detail of this dream... This was already hard to tell my friends. But basically me and a ton of my friends were kidnapped by this crazy phyco and we were tortured in all these crazy painful ways. The wounds from this torture got infected on most of my friends and it ended up killing them... After a while of that there were 11 of us left (including me). He forces me to do the torturing from now on to my remaining ten friends. Soon I get mad and I somehow am able to punch him, so he told me to torture them again. Instead I told him to give me the total of all their torture knowing it will probably kill me. He agreed and started strapping me to the torture machine, he told the guard to go get my ten friends and to tell them what is going on. He brought them to me to say goodbye, one of them was really mad at me for doing this, and squeezes me so tight I think she may kill me before the phyco does. He chains them to the wall in order to watch. Next the torture is an electric shock. And taking it for ten people makes it one large shock that again will probably kill me. He counts down from three and between two and one I look at my friends with tears in my eyes, an silent goodbye. The shock kills me instantly. He chains my friends and they run to my limp body. Then the dream switches to a few days later. He had used this device to bring me back to life , I'd gotten a proper scolding as soon as I came back. And I promised that I wouldn't take the torture and I had to torture them more. A few days later he told me that he was going to kill my friends and so I lashed out again. He knocked me out. I woke up in a different room with a gun in my hand, I held onto it just incase I needed it. Then I saw all ten of my friends lined up heads down and blindfolded.. and only tied to the ground by their legs their arms were free. I was starting to figure out what was going on. The phyco came on a loud speaker asking "Figured it out yet?" "Yeah I think I have..." tears are now forming in my eyes. "I'll explain just in case you are wrong. Ten bullets. Ten people. If you don't do it I'll kill them, anyone else you know, and all of north america. You will never be able to forgive yourself." "Either way I won't forgive myself" "Better do it now" He starts counting down, I know I have to kill my friends before he reaches zero. I'm balling now. I walk over to my friends. "It okay" one of them puts their hand on my right hand, the one with the gun. She moves the gun up to her head and puts my finger on the trigger. "Be a hero. Pull the trigger, please we all would rather die than kill all of north america." With her other hand she wiped away my tears, then she put that hand on my heart. "Please" "I-I'll miss you" "We know. Now please on each of us just pull back you finger." (Just know she is still doing this all blindfolded by the way but it's a dream it doesn't have to make sense) Finally after a bit more coaxing from everyone else. I shoot them. I fall to the ground balling. Their blood moving down from their head gathering on the flood right under me. Then the SWAT team breaks into the building and I think I faint. I wake up in a hospital. My recovery is very emotional. And half way through I realized if I had refused to kill them the phyco would have been captured before he could have killed anyone. Then I wake up.....

I have this dream over and over.... it's really scaring me. I looked up on dream interpreters what it might mean but nothing it said about the dream fit right.... I just need someone to tell me what this means... and if it's normal to have weird vivid dreams like that alot. And what I should do.... Thx
