Ok, in nearly all my dreams i get either shot or stabbed, and its worrying lol

Dream 1
I had discovered an upsidedown world, exactly like this one. There was an upsidedown me and upsidedown friends...etc
I decided to ask them if they wanted to be friends, they said yeah sure and stabbed me in the back (i still remember the pain) they killed all of us (thats all i remember i was about 5 years old at the time)

Dream 2
I was with my friend at home, and a stranger appeared trying to knock the door down. He got in a started shooting at my friend, i jumped in the way taken the bullet and then he ran out (thats all i can remember from that dream i woke up)

Dream 3
I was on holiday in Switzerland with my friends, then the next thing im a hostage (i dont remember how i got in that situation)
I was sitting on the floor with the terrorist yelling in my face and at others. He ended up pulling me up off the floor, shooting my leg...then as he put me down he shot me in the head

Dream 4
I was an assassin, and i was with my best mate who ive never seen before in real life. He was about to be married to his pregnant fiancee the next day. He was out (as expected) and she was about to give birth. As she was getting in her car, i killed her and her mother that was there (i have no idea why). Later he found out i had done it and had sent assassin to kill me, they had shot me several times (which didnt hurt), but i still fought back killing them.

I never die in any of these dreams though O.o Why cant i have a nice not being shot at dream for once lol xD
