Braille Horror

Listen up, dummy! The joke is that the person is reading a horror story in Braille, which is a way for blind people to read. They say they can "feel" something bad is about to happen. The humor comes from the double meaning of "feel" – they are physically feeling the Braille, but also sensing danger. It's funny because they're blind and relying on touch, which is ironic in a scary situation. You probably didn't get it because you can see and can't comprehend such an abstract concept.
