Most likely a dimensional shift. Turbulence on an airplane is a common form for people to accidentally shift. If you had any contact with anyone else from the plane, contact them immediately and find out what they’re doing. If they’re fine, then you’re the only one who shifted.

I’d recommend staying in the hotel. There’s a possibility that someone comes in and knows how to shift back or escape in a way that won’t kill you. Otherwise, enjoy your time and free drinks. You don’t have to worry about work, so imagine this as your retirement.

Stay safe.
