ABSTRACT
Expansion-related vertigo occurs in analysands who realize that they keep puffing themselves up as if they needed this continuous expansion to feel that they are alive. They give one the impression that they will allow nothing to stand in the way of that continuous expansion. Actually, they have difficulties in determining the boundary between their ego and the object, and they begin to present vertigo the moment they realize that they have a need to get close to the limits of the object if they are to discover those of their ego, lest their ego spread by a form of expansion that robs it of shape and consistency.
