I would like to preface this with the fact that I am not afraid of the subway.
Living near Boston I use the subway, called the T, quite a bit. Red line, Orange line, Green line...all the colors of the filthy Boston rainbow are familiar to me. I even know the buskers, like that Sammy Davis Jr. impersonator who sings along to his CDs or scratchy throated bum who once sang the dog version of Jingle Bells. My ass has never been grabbed nor have I ever been robbed.
But I have small panic attacks on the subway sometimes. You know when you're on the train and you're zipping along in the black tunnels under the city and all of a sudden the train stops? You're stuck in an inky tunnel and you can't even see the walls from the smudged windows. Immediately when this happens my brain goes straight to a vampire attack.
It's not logical, but there it is. My brain seems to think that subway tunnels are the perfect place for vampires to chill out and wait for a subway car to come along so they can rip it open like a Twinkie wrapper and get the gooey filling inside.
Whenever the train slows down without a station in sight my heart starts pounding a bit harder and it becomes difficult to take a breath. Again, I know that there being a vampire attack on the subway is illogical and kind of dumb, but I just can't seem to help it.
