My idea

My idea is based around the power to walk through walls but not return through them.

There would be a crab shot from right to left, you would see both sides of the wall - An empty side on the right and a person clearly frustrated on the left

There would be a match on cut action and you would hear the subject better - talking to the wall

The camera spins round after a door is heard closing and someone walks in and says "Are you talking to a wall" - The subject replies sarcastically at the person in the door and returns to trying to get through the wall.

The camera returns back to the third shot and the subject continues cursing at the wall.

The camera cranes back and the subject runs at the wall, Passing through it

The camera pans around from the 'victory shot' and there is a family or a class going on and the subject runs back at the wall - thus knocking himself out.

The character previously seen mocking the subject, walks through the open door, pointing out the subject's obvious mistake.

Cut to black.
