"I broke my skull on Friday the 13th," he shared in an August 10 interview with Variety.
"I woke up 12 hours later at the bottom. I was trapped."
The 24-year-old said that he suffered a broken skull, internal bleeding and broken fingers from the fall. And after coming to the conclusion that "they wasn't gonna find me down there," Cloud entered "survival mode" and decided to save himself.
"I eventually climbed out after-I don't know how long," he recalled.
"It was hella hard to climb out, because my skull was broken, but my skin wasn't, so all the bleeding was internal, pressing up against my brain."
Once he made it out, Angus took a bus to his mom's house. After making his way home and not being able to finish a sentence in front of his mother, Angus pitched that he was gonna go to bed. Thankfully, his mom stopped him.
"I would have died," he noted.
"She gave me some water, and I started throwing up hella mouthfulls of crimson red blood."
As for the scar's story, the mark came as a result of the life-saving operation at the hospital.
"They cut my head open," he shared. "They put some screws and a plate over where I broke my skull and-s--t, sealed me back up, and that was that."
Reflecting on the experience, he said that while "the brain is so fragile," he is "so blessed to just have minor brain damage."
