2) A Night Gallery episode where a hypnotist works with an utter hypochondriac, and gets him to the stage where he can trigger the complete symptoms of any disease in his subject by a planned sequence of knocking sounds. This also means that be can turn the chap into an absolute stud too, since he can mimic complete and utter perfect physical health.
The hypnotist's wife is unhappy in their marriage and, as so often happens in such stories, she falls for the newly Adonis'd hypochondriac. The hypnotist finds out, but resolves to do nothing.
He then prepares his ultimate test, death itself. He will get the hypochondriac to appear to die, and then return him with a sequence of knocks. Over the wifes protestations, they perform the experiment, but whilst he does instantly stop breathing and has no heartbeat, indeed rigor mortis has set it, it appears that it's gone too far as he can't be revived by the knocking pattern. The hypnotists tries over and over again to make it work, but nothing happens. Ultimately the poor sod is declared dead, and is buried.
I'll leave this bit texted out, just in case someone hasn't seen it, and doesn't want the end spoiled. Highlight to read
It's only several months later, when listening to the recordings of his sessions with the chap, that the still distraught wife notices that the hypnotist used a different sequence of knocks when setting up the death state, than the one he used to revive him. Realising that at some level he was so jealous of the guys attraction to his wife (and vice versa) that he unconsciously WANTED him dead, the wife, now out of her mind with grief races to the cemetery and makes the correct series of knocks on the door oh the mausoleum, and sure enough he wakes up and comes towards her out of the shadows ... Now if only she'd waited long enough to hear her guilt-ridden husband begging her NOT to try and revive him, as he'd been through an autopsy and embalmed.
(I confess that watching this at half past midnight by myself, in a dark house, at the age of 15, I was so completely and utterly shit scared I literally had to change channels because there was no way on God's green earth I wanted to see what he looked like onscreen, my imagination was already going into overdrive. In retrospect, given the budget of the show, it was probably infinitely scarier in my head that it would have been on screen)
