going back to my "growing up days", watching films with my mates or a bird, in no particular order, films that scared the bejesus out of me:-
nightmare on elm street
the omen
poltergeist
the shining
with a special mention to Salems Lot on TV (the boy floating outsdie his mates window!

)
nowadays, the most recent would be the ring. purely for a great bit of timing from a phone call i had!!
