hmmm, i think it would have to be 'Psycho' because i watch it almost every time i see it on television.
i still do not take a shower because of the shower scene in 'Psycho.'
i also like 'scream', 'fright night' and 'halloween' for a good movie i can watch without scaring myself to pieces.
i started watching 'paranormal two' but could not finish it.
