Does any one remember this story? A man is put under hypnosis at a party and whilst under he sees a man trapped in a lift, a cage type that just goes between two floors in a mansion. When he is brought round he is most upset by the vision and proceeded to track the mansion down. He eventually tracks it down with the help of an estate agent. It is in an out of the way place and has not been lived in for years. They enter the building and look around taking the lift to the first floor they have a look round there but can find no evidence of any such event happening. The estate agent exits via the staircase; the man searches further but cannot find any clues. He enters the lift and half way down the lift sticks. He is trapped, he had a premonition of his own doom. I thought this was from the series One Step Beyond but I have a brief episode guide but cannot find any mention of it. Does anybody else remember it?
