Macabre

"Man lives in a world of time and space; he lives in a spectrum of the universe.  When he ventures beyond this limit, he is in the unknown a realm where strange forces are brought into play.  When man attempts to misuse these forces, he is sometime destroyed.  This is Macabre."

Macabre is an AFRS series creating at the end of radio's golden age.  Lasting only eight shows, Macabre was exceptionally well written and the actors are unknown but quite believable. 

The first show in the series called "Final Resting Place" features a newly wed groom willingly buried alive for $500 to pay off his car.  The scene of his wife clawing at the ground looking for him is exceptionally well done and frightening.  The groom eventually wakes up from a hypnotic state buried alive and panics—very convincingly.
