Make your blood run cold
Meaning
To cause a feeling of intense fear, horror, or dread.
Origin
Imagine the chilling grip of pure terror, a feeling so intense it seems to freeze you from the inside out. For centuries, people have observed how extreme fear can cause a sudden physiological shift, constricting blood vessels and draining warmth from the skin, leaving one feeling icy and stiff. This visceral response—the sense that one's very life force has turned cold—crystallized into the vivid phrase "make your blood run cold." It's a powerful metaphor, capturing that primal, paralyzing moment when dread washes over you, transforming warmth into a terrifying chill, as if the lifeblood itself has been replaced by ice.
Examples
- The sudden, piercing scream in the dark alley made my blood run cold.
- Listening to the ghost story on a stormy night, her blood ran cold as the wind howled through the eaves.
