Rocker Sammy Hagar recently discussed his extraterrestrial viewpoints in an interview on Dr. Drew’s HLN show.

“I’m dreaming,” Hagar begins. “I see these guys in my head … they were beams of light … there wasn’t language spoken. It was a telepathic thing.”

When Sammy woke up, he said it put him on a quest to find out his dream’s meaning.

“I think it was a download and upload situation, like an experimental thing, like I was some guinea pig,” Hagar told Drew.

Sammy truly believes we’re not alone.

“Anyone who says, ‘there’s no one in this universe … we’re the only life in this whole big vast universe;’ they’re crazy.”

“I absolutely agree with you,” Dr. Drew said.  “I believe that life gets catapulted forward from catastrophic events in the universe… but I’ll remain skeptical of the guys with the white light.”

Be sure to watch the full Sammy Hagar interview as it airs on Dr. Drew’s HLN show on Monday, April 4 at 9 p.m. ET/PT.
