This is an unfinished thought that occurred to me the other day. I haven't worked it all out in my mind as to if it's significant or just folly.

The subject of spirits and vampires with fangs:

What are fangs for?
Snakes use them to inject
Vampires use them to extract

What do spirits use them for?
I'm pondering on both above uses as the situation calls for.
~Inject the idea and/or knowledge of their existence
Or extracting the disbelief.
~Of course, if it's malevolent, then it could be injecting negativity and extracting positive energies.
~Or as Alisa said in an early post something like, they may use the fangs for effect like a show of strength or power.

Like I said, this is a loose unfinished thought.
I post it for your perusal and to add your thoughts too.

What do you think the fangs are for?

I look forward to reading your thoughts on this.
