Are you more of the emotional type? Do you consider yourself dark and expressive? If so, it seems that your ghostly counterpart may be a banshee.
Banshees are known for their wail of death--they usually appear before or after a loved one has died, and unleash their grief in the form of a loud cry. Like the banshee, you aren't afraid to hide your emotions. When someone hurts you, you let it be known, whether it's with tears or harsh words. No one can accuse you of NOT being in touch with your feelings... (Just think--you've saved yourself years of therapy!)
Like all things, keep in mind that sometimes it's better to think things through than just react. After all, a banshee's scream is known to frighten the masses. You wouldn't want to do that...(or would you?)
