It's gotta feel like they've been abducted by existential cosmic horrors. I can just imagine they tell stories of these horrid abductions.
"They just snatched me up, these freakish giants with squishy, lumpy, fleshy exteriors. They tied me down, man, they tied me down and drained my blood! I'm pretty sure they thought I was dead, I played dead. They just tossed what they thought was my corpse back in the water. You gotta believe me!"
"I believe that you believe, Bill. We're gonna find you some help."
