Aircraft Turns - is there a 'pre-turn'?
In cruise, there are no opposite turns that precede every turn.

Human senses and the inner ear are very good at playing tricks, in fact pilots can't judge turns if they have no visibility (e.g., in clouds) without using their flight instruments.

Judging an aircraft's bank from a passenger seat is almost impossible at night, in clouds, over sheets of ice, over hazy oceans, etc.

On a commercial flight, the water in a cup remains level in the lateral during coordinated turns, that's because the load pulling down on the aircraft will still be pulling down perpendicular to the floor.

A shallow roll to the right or left could be just the plane correcting its course in a gust or so.
