Eidolonic ascension/descension experience 

What happens when your body perceives a change in elevation and proceeds to make you think you are about to step up or down only to jar the experiencer into a self conscious awkwardness and sense of mistrust in their own perceptions.

I saw Marcus throw his back out during an "Eidolonic ascension/descension experience" while taking the stairs.
