You still haven't answered one question, where these turns based on you seeing the horizon move out the window, or you "feeling" the turns?
I've flown in IMC into airports where I know the routes and procedures by heart, at one time I could've sworn we made a 360 on the way in. Like you I actually was so curious I mentioned it to the flightcrew, who said it'd been a perfectly normal STAR with no vectoring.
My point being, if you based it on feeling things, and FR24 does not even show one of the turns, they most likely never happened.
