I am a chicken too and can't watch the scary bits in a film. Neither can I take suspense, nor gory bits. My D and I watched 'The Fall' last night and, as the first two thirds were taken up with a graphically presented operation I hid my eyes for 40 minutes with my DH saying, 'Don't look yet. Wait until I tell you you can look. Definitely, don't look NOW!'
I have done a few of those 'Test your Personality' website quizzes for things like introspection, sociopathy (!!), sensitivity, narcicissm,Aspergers, emotion recognition in others and so on and I have confirmed what I suspected, I am hyper aware and hyper sensitive. In short, a bit of a snowflake.
