I'd cry.
Start praying my death would be swift or wake up from the horrible nightmare, kneel and keep praying.
Or tell myself this is just a nightmare.
Quietly find a disguise and head south.
I'd do the Harlem Shake .... It's the right thing to do
I'd set a world record for swimming 200 km. That's the width of the strait between Korea and Japan.
Since this will never actually happen, I would definitely quit whatever substance that caused the awful hallucination.
I'd search for Dennis Rodman and see if I could hitch a ride home with him.
Fire my travel agent . 😉

This one's for Rooster:
I'd quietly execute my captors, capture their weapons, commandeer whatever transport is available, supply myself by hook or crook, moving as swiftly as possible toward the nearest shoreline or airfield.
Since forcible abduction is the only possible, realistic cause of my presence there, everyone blocking my path out would face their fate, until I am either recaptured, killed or repatriated.
Get out of there
I slowly go back to sleep in hopes of getting awake somewhere else. Maybe this all could be a nightmare.
Not much because as soon as they saw you?
