I don't know if it's common with people that exhibit antisocial personality traits, but I've never had a scary dream, nor any kind of nightmare or night terror. I've had dreams that would be considered some of the most terrible nightmares for other people, but to me the dreams are really fun or seems totally normal.

I think by mentally preparing myself for the absolute worst things in life carries over into my dreams... so when things go totally wrong my mind has a solution for it or it doesn't bother me.

Like, getting trapped underwater and knowing that you will drown - I never panic because for some reason I can always just breathe in the water so then I have fun breathing the water.

I've been killed more times than I can count in numerous ways (stabbed, shot, nuclear holocaust, etc). I either respawn like in a game, or I peacefully accept it as my fate.

You just need to somehow face your fears or they can overwhelm you in a dream. Try meditating on some of the things that disturb you the most.
