7. Falling
Falling from the height is not deathly only because of the breaking on the sidewalk. There are medical proves that some people who fell actually died during the fall, so they were not able to feel the true pain. But, is there any worst thing that being aware of the death caused by hitting on the ground and not be able to stop that? To be added to this list we can mention a special variation of this death, falling into a volcano, which, let be honest, cannot be compared with any other creepy death we know.
