One way to gain a sharp insight into your characters is to assign them a Halloween role, specifically that of a monster who would be their alter ego. Many times, the best way to learn something about your characters is to ask yourself a question, and then “ask them.”
For example, my assistant said he would be the Wolfman because he loves the night, is only a monster once in a blue moon, and always has easy access to food.
Then he said I would be The Wicked Witch of The West. I was offended until he explained it was because I “like to look into that metaphoric crystal ball and see what others are doing.” I’m not really sure that’s better.
Anyway, take a moment to decide who you would be and why, and who the main character of your story would choose to be. You might be “scared” to discover just how much you learn about yourself and your character with this Halloween exercise.
Good Luck and Happy Writing!
