Philosophical implications of derealization disorder

The present paper offers an analysis of derealization disorder, a disorder in which the experience of reality is altered. In this respect, usually, real objects are experienced as mind-independent and as offering motoric interaction. These two features seem to be responsible for our experience of objects in quality of real objects. Then, a crucial question is the following: what aspect of the experience of reality is derealization, in quality of a disorder of reality, about? This paper suggests that, in the case of derealization, what is disrupted is the experience of mind-independence, but not the experience of possibility for motor interaction. By doing so, however, the paper also suggests something important on the relation between these two experiences, namely, that they can be, contra any alleged, very general intuition, disjointed, as the case of derealization shows.
