Is it normal to imagine bad things happening around me all the time?
I walk to work through a major city - crossing roads walking past train and bus stations etc - and by the time i've got to my office, i've been run over twenty times, reversed over, i've seen people get crushed between cars, hit by buses, pushed in front of trains - everywhere i go and everything i see i imagine whole scenarios where bad stuff plays out. Even when I'm just walking my dog in the park i will suddenly find myself imagining that he runs off and gets hit by a car or something. I get so engrossed i stand there staring at the ground and forget where i am. Is this in any way normal or common?
