Imagine that you are in a comfortable cinema.
Sit down in the most comfortable chair you can find.
The kind that you would almost be concerned you might fall asleep in if the movie was a bit boring.
Now imagine you can float out of your body and into the projection booth.
Stand behind the solid glass of the projection booth and look down into the cinema until you can see the back of your head down there looking up at the movie screen.
You are going to watch a film of a traumatic memory.
However,
Before you do,
Just mark two spots in the film,
A few frames before the event ever happened,
And another few frames after you came out successfully the other side of the event.
Place a still image of the before frame onto the screen.
Safely behind the solid glass of the projection booth,
Watch yourself down in the comfy cinema,
Watching the film of what happened up on screen all the way to the moment after you successfully came out the other side of whatever that event was.
When you get to the end,
Freeze the after image up on the screen.
Now run the film backwards as fast as you can,
See all the images going backwards,
The sound running backwards,
Everything moving in reverse,
All the way back to the beginning before it ever happened.
Now go back and place the still image of the before frame back up onto the screen,
Safely behind the solid glass of the projection booth.
Watch yourself down in the comfy cinema,
Watching the film of what happened up on the screen all the way to the moment after you successfully came out the other side of whatever the event was.
When you get to the end,
Freeze the after image on the screen.
Now run the film backwards as fast as you can,
See all the images going backwards,
The sound running backwards,
Everything moving in reverse,
All the way back to the beginning before it ever happened.
And we're going to repeat this process a few times until the memory has lost its emotional impact.
