I find were-wolf bite as a fatal encounter in a life's person that sends them evaluating themselves and have hallucinations of how they planned about life but how they turned out.
I have had such fatal experiences and could totally relate to hallucinations where we relive in our thoughts and feel guilty over and over and there is no way to turn it off.
Please share any metaphorical elements you find in TVD.
Also, the blood lust as a vampire which is hard to control. I can relate to it. Ofcourse, metaphorically. It's about things in life where we are forced to do it and find it inevitable in situations that makes me a "stereotypical bad" person though i am not and its the circumstances that made me do it.
