Paul Simon leaned on dreams he had while sleeping to create his latest studio album, "Seven Psalms."

"The dream said, 'You're working on a piece called 'Seven Psalms,'" Simon recently shared with CBS News. He told the outlet that he woke up, wrote down the idea on a legal pad in his cabin in Texas where he lives with his wife of over 30 years, Edie Brickell.

He said since the idea came to him in a dream, he needed to "wait 'til there's clarification" on what he's supposed to do. Lucky for Simon, he got that clarification. 

"Yeah, it did come, as guitar pieces," he told the outlet. Simon shared that the words for his album came to him later, again through a dream. His entire creative process behind his most recent album will be showcased in an upcoming documentary, "In Restless Dreams."

In the documentary, Simon said, "I would start to wake up two or three times a week between 3:30 and 5:00 in the morning, and words would come. I'd write 'em down and start to put it together."

Some listeners have interpreted Simon's "Seven Psalms" as a reflective about mortality and death, particularly with a song titled, "Wait."

Simon insisted otherwise. "Of course, I'm 81 years old. Of course, I think about it. But I mean, is it pressing on me? No, it's not." 

When the musician was asked if he ever questioned where his dreams and visions were coming from, he replied, "I don't even know if I wanna know."

"It's just, it's ‘there,’ and I'm grateful for it. It's been there most of my life," he elaborated. "When I wrote 'The Sound of Silence' and I was 23 years old, that was probably the same kind of phenomenon. But at that time, I just thought, ‘Oh, this is kind of my best song at the moment.’ And the same thing with 'Bridge Over Troubled Water' where I thought, ‘Hmm. Better than my usual. This is good.’"

Simon has been facing some set-backs in his career and his health. The 81-year-old singer revealed in May that over the last two or so years, he has lost most of the hearing in his left ear.

"I started to lose the hearing in my left ear," he told the outlet, adding, "about two years ago, two-and-a-half years ago. And at this moment, it's, I think, 8% hearing in that ear."

He continued, "It's upsetting. I can still hear well enough to play guitar and write. But I can't hear well enough to play with five or six musicians. Maybe that's fine. Maybe there's something to be learned from that?"

Even with struggling with his hearing loss, Simon has not stopped creating music. "I just started to write recently," he shared. "I've written two songs. As long as I can write and sing, I'll make records, even if it's just for myself."

In 2018, Simon announced he was retiring from touring. In a social media post, he wrote, "I feel the travel and time away from my wife and family takes a toll that detracts from the joy of playing," adding, it "feels a little unsettling, a touch exhilarating, and something of a relief."

His last live performance was at Newport Folk Festival in July 2022. Simon revealed that he's hopeful that will not be his last live show. 

"Well, I hope not," he told CBS. "I really wanted to perform the 'Seven Psalms.' I haven't given up hope, but I'm prepared to accept that I might not be able to."
