Can your characters ever feel you watching?

Writers are voyeurs.

We watch the lives of our characters play out; ever intimate, ugly, euphoric moment.

We know the contents of their pockets and what lies under their bed; we know their deepest fears better than they do; we know how they love and why they suffer.

But can you ever feel them looking back at you?

Maybe they notice an overly serendipitous change in events; a book that is out of place, a misshapen doorway, moonlight that is slightly too bright. They feel you observing their psyche; they question who they're falling in love with.

We are more noticed by our characters than we would imagine.
