Superstar Paul McCartney and one of the most well-known and talented musicians on the planet has revealed that he believes he once saw “God.”

Speaking to the U.K.’s Sunday Times, McCartney said that a psychedelic trip led to him believing in an afterlife.

“We were immediately nailed to the sofa. And I saw God, this amazing towering thing, and I was humbled,” McCartney said about a time he ingested DMT (dimethyltryptamine) in the company of people such as art dealer Robert Forster.

“And what I’m saying is, that moment didn’t turn my life around, but it was a clue.”

The musician continued, “It was huge. A massive wall that I couldn’t see the top of, and I was at the bottom. And anybody else would say it’s just the drug, the hallucination, but both Robert and I were like, ‘Did you see that?’ We felt we had seen a higher thing.”

McCartney also opened up about his feelings about the current state of the world.

And he is not impressed.

“Violence and arrogance are back,” he said.

Though he didn’t name President Donald Trump by name — it’s not much of a stretch to believe the president is part of what the celebrity thinks is behind bringing back “violence and arrogance.”

“It’s like how fashion goes in cycles, how bell-bottoms came back. We were heading toward sense, but we are into the next pendulum swing now. That happens in life,” McCartney said.

McCartney — who wrote “When I’m 64” along with scores of other major hit songs for the Beatles along with John Lennon — is 76 now, and he said he believes that he has hope for the future.

He believes Britain was in a bad state in the ’70s and made a comeback — and that the world can do the same. “Cemeteries were left to rot. We felt we were heading to Armageddon, but it cleaned up,” he said.

McCartney told the Daily Telegraph last year that he believes Donald Trump has unleashed the “ugly side of America.”

“He’s unleashed the ugly side of America. People feel like they have got a free pass to be, if not violent, at least antagonistic toward people of a different color or a different race,” he said.

He added, “I think we all thought we’d got past that a long time ago.”
