Here's how we can break down the meaning:
* Carcasses: This refers to dead bodies.
* Bleed: This suggests a reaction, a response to something.
* Sight of a murderer: This implies that the presence of a killer triggers a reaction in the dead.
Possible Interpretations:
* The impact of evil: The phrase might be used to convey the idea that even in death, the presence of a murderer is so powerful and unsettling that it can evoke a visceral response. The "bleeding" could symbolize the lingering horror and fear that lingers after a murder.
* Spiritual connection: The phrase could suggest a spiritual connection between the dead and the living, where the dead are aware of the presence of the killer and react accordingly.
* Poetic license: The phrase could be used purely for its dramatic effect, without a literal meaning. It's a way to evoke a sense of unease and amplify the horror of the situation.
It's important to remember: This is not a real phenomenon. Carcasses do not bleed at the sight of a murderer. The phrase is likely intended to be metaphorical and evoke a sense of unease or fear.
