I want to die in my sleep peacefully like my grandfather, not screaming in terror like his passengers.

Our reading
An editorial interpretation.
The opening sounds like a wish for a peaceful death, until the reference to passengers changes its meaning. Their terror suggests that the grandfather's sleep had dangerous consequences for others. The dark joke depends on that abrupt reversal of an initially comforting picture.
