laying or lying?

I had a house warming party with a few colleagues in college years ago. It lasted way into the night and though I don’t drink, everyone else did. I ended up falling asleep on the couch in the living room. Early the next morning, I awoke to find myself shirtless and barefoot. Next to me was a younger male colleague passed out laying opposite me with his face touching my bare feet. I wiggled my toes making him groan.

Shouldn't it be "lying" instead?

Thanks!
