This happens to pax as well. I was on a AF flight recently and slept most of the way, one of the FA's woke me as we approached the airport and I was convinced we were arriving at CDG and I would soon be home....only to find out we had landed in Yerevan....then it all came back to me as I woke up properly......I often get a similar sensation when I wake up in a hotel room, it takes me a few seconds to work out where I am.
