Coreas was walking his dogs on Oct. 3 when a lightning bolt seemed to come out of nowhere. Coreas collapsed instantly.
Two workers at a veterinary clinic next door rushed to his aid and performed CPR until they could feel a pulse.
"It's crazy. They ran to me and did something, not just standing there," Coreas told Eyewitness News on Oct. 7. "I'm lucky to be alive, and I just want to go on living my life. And I have a story to tell."
