"HORROR WANTS PSYCOED"

In The Book of Horror: The Anatomy of Fear in Film, it says there's seven scare tactics in horror movies -- 

1. dead space

2. the subliminal

3. the unexpected

4. the grotesque

5. dread

6. the uncanny

7. the unstoppable

I keep forgetting what they are so I came up with a mnemonic:

PSYCOED

as in

HORROR WANTS

P        ervasive       (the subliminal)

S        hocking        (the unexpected)

Y        ucky            (the grotesque)

C        orporeal         (the unstoppable)

O        dd                  (the uncanny)

E        mpty             (dead space)

D        read      

I think when it comes to scares in movies, the name of the game is Dread and there’s six ways to having it. 

As for why Corporeal for Unstoppable: I think the unstoppable-ness of the Horror is usually most dreadful in scenes where the Horror can wreck people in spite of a capacity to be targeted. I figure what The Book of Horror calls The Unstoppable must be the Horror's terrible transcendent impossibility when its impossibility seems most scraped out -- when we have to deal with the fact that it is indeed there and it really did all that, and so we may fail to stop it purely because it is just that good.
