You're that person

You were trying to put order to the mess in the attic for the masters of the house when you fell upon a mask. As you were observing it, wondering where you would put this artefact, it flew out of your hand, pulled by an invisible force and crashed onto your face with high velocity. It caused you to stumble and fall to the floor. You try to take the mask off, but it doesn't seems to budge from your face.
