for me, it depends on the medium. if it's movies, i'm more scared with horror flicks. i normally will have difficult time sleeping after watching movies with monsters and the gore alongside it. interestingly if i'm just reading about it, i could also just easily shrug the monsters off as fiction and imaginary. while psychological thrillers scare me, the level of fright is different when just watching it. if i'm watching it, i'm not as scared as when i'm reading it. curiously, even if i'm super scared while reading the thriller, i can't seem to put the book down and i won't have problems sleeping after reading it.
