Lyric discussion by HowardTCo 

It might be more about drugs and death. The narrator is a drug addict and the ghost is a girl/lover that OD'd. She is warning the narrator of her fate.

White eyes might mean getting off the drugs as opposed to red eyes that is common from drug use.

White eyes might also refer to eyes rolling back into your head; perhaps during a seizure.

Either way the white eyes (being sober or ODing) are scary for the narrator. The girl might just be a hallucination too.

The second verse might represent the narrator getting clean but the former lover still haunting him. He might be urging to relapse ("It's gets so quiet I can hear myself bleed")
