What's going on when I'm getting a "kink in my neck" after sleeping in an odd position?

I must have slept weird but I woke up with a kink in my neck. What happens that causes this?

Tissue viscoelasticity. The extensible elements in your musculoskeletal system have taken on a certain 'set' after prolonged immobilization. That's why normal sleep is best in a large bed to permit frequent involuntary re-posturing during sleep. Like the flat spot that forms in a tire while the auto is parked. A bit of bump remains but soon disappears with flexing and heat.
