Dr. Christopher Kerr and his team have been documenting dreams or visions of dying patients for years.

They've found that the dreams are often comforting and make death less scary.

It turns out, when we have little time left, many of us may see the people we miss the most.

They've recorded many of the interviews.

A man named Horace explained one of his dreams: "My wife all of a sudden appeared."

A woman named Jeanne describes how vivid they are: "I remember seeing every piece of their face. I mean, I know that was my mom and dad and uncle and my brother-in-law." She continued: "I felt good. I felt good to see some people."

A patient named Maggie dreamt about her sister, who had passed away before her.

"So I said, Beth, you've got to stay with me," Maggie said. "I'm alone, stay with me. She says, 'I can't. Not now."

But then, her sister gives her a message: "And then she says, 'Soon we'll be back. We'll be back together."
