Dark apparition

You cannot quite focus on the shape of this thing. It wavers and shifts as an image seen through dark waters yet each shape it assumes has some aspect of horror and bloody death. One form is that of a corpse mutilated beyond words with arms hacked to stumps yet tipped with shining claws. You shiver as it changes in form to that of a waif horribly burned and scarred so that her features run like melted wax. Then it shifts yet again into something apparently torn apart by huge razors...flesh hanging in sheets that blow in some ill-spawned breeze like leaves of sea-grass in the current. You turn your head and gag, being unable to bear any more.
