You and your best friend, Noah were picking matching costumes. You guys find vampire costumes at the back of the store in a weird black box. You guys get the box and go to his house to try it on.

You both go into the bathroom and get dressed in the vampire costumes. And when you do..

The lights start flickering and you feel a weird tingling sensation on your body.. it goes pitch black.

Then the lights turn back on and you both look in the mirror. There's no reflection. A beat of surprise ran through your chest. You move your hand to your mouth and feel.. fangs..?
