Is something wrong with me?

Horror movies or just learning gorey stuff (like when we learned about the donar<-typo?, in social studies) make my stomach feel sick, but I find it sort of interesting at the same time. Am I messed up? Like right now, I just randomly clicked on the movie 'Halloween' and it makes me feel so sick when that kid kills people. I find it sort of interesting though (not the killing but more like the story). Im sort of feeling freakout out and so messed up right now. Like when I learned about the donor party I felt sick to my stomach but a little interested also. )*: please help.
