A chill ran through my blood

In the Netflix series, “Evil Genius”, courtroom artist Kevin John uttered this malaphor when the defendant in the infamous Pizza Bomber case walked into the courtroom.  It is a congruent conflation of “a chill (or shiver) ran down my spine” and “my blood ran cold”, both describing a sensation of fear or dread.  “Ran” is in both expressions, probably contributing to the mental hiccup.  Also “cold” and “chill” are similar meaning and sounding words.  A tip of the toque to Mike Kovacs, aka “The Malaphor Hunter”.
