Weren't the dementors described as "gliding" as opposed to "walking?" I remember that they had a stupid conversation about it in the fifth book. Sorta. Either way, as we all know most directors are physically incapable of telling the difference betwen gliding and flying, as is shown in a famous movie someone probably made. So that's probably where that came from.
