Sometimes it feels like it’s only happening to me – but that isn’t true

Sometimes, when I ride in a car, I stick my arm out of the window.  Whenever I do this, I can imagine – feel – my arm being hit by another car, mailbox, building.  The sensation of my arm being sheared off.  It is so strong, I pull my arm back into the car.  Without fail, I do this again, the next time I ride in the car.

There are many other odd things that I feel – sense – experience.  More on those later.
