Nina De Santo was about to close her New Jersey hair salon one winter's night when she saw him standing outside the shop's glass front door. It was Michael. He was a soft-spoken customer who'd been going through a brutal patch in his life. She'd listened to his problems, given him pep talks, taken him out for drinks. When De Santo opened the door that Saturday night, Michael was smiling. Nina, I can't stay long," he said, pausing in the doorway. "I just wanted to stop by and say thank you for everything." They chatted a bit more before Michael left and De Santo went home. On Sunday she received a strange call from a salon employee. Michael's body had been found the previous morning -- at least nine hours before she talked to him at her shop. He had committed suicide. If Michael was dead, who, or what, did she talk to that night? Today, De Santo has a name for what happened that night: "crisis apparition." A crisis apparition is the spirit of a recently deceased person who visits someone they had a close emotional connection with. As they chatted face to face in the doorway of her shop, De Santo said they never touched, never even shook hands. "I'm in a really good place now," she recalled him saying. And when she held the door open for him, he refused to come in. He just chatted before finally saying, "Thanks again, Nina." Michael then smiled at her, turned and walked away into the winter's night.
