Why do I react so strangely in common dreams?

I know that dreaming of somebody trying to kill you and also dreaming of being out in public without clothes are common. However, when I try to look up the meaning online, I can never find an answer that seems to apply to me because the way I react in these dreams is different than what the interpreters assume. In my dreams where somebody is trying to kill me, I am usually frightened, yes, but mostly I have a lot of fun trying to outsmart and evade my pursuer. I come up with elaborate plans that allow me to escape and I end up enjoying it. In my "naked in public" dreams I am usually freaked out for a split second, until I realize that everyone around me either doesn't notice, or doesn't care. Then I pretty much think "awesome! I can go around naked!" And go about like that for the rest of the dream...
