Definitely Edgar Allen Poe's stories of catalepsy and being buried alive, then waking up to find yourself chatting to the worms hammering on the coffin awaiting your demise. The sound of the heavy breathing and panic to scratch yer way out .. then to be discovered later with broken off bloody covered fingernails and frozen look of absolute terror on the face .. brrrrh ...
Only film a friend and I walked out of .. some sort of trilogy of his I think .. twas either at the old Empire/Princess cinema and had to forget the whole thing in the Derby with a 'few' gin and oranges.
Took my daughter (think she may have been about 14 ? ) to see Jaws .. the opening scene with the music, when that big fish dragged the swimmer down, had a profound effect on her life. Couldn't sleep for weeks and has never paddled in the sea since.
