What does disassociate mean here?

Solution 1:

The usual spelling is dissociate. In its use in psychology as a mental action, state, or event, Wikipedia gives its definition as follows:

Dissociation is any of a wide array of experiences from mild detachment from immediate surroundings to more severe detachment from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a loss of reality as in psychosis.

The usual dictionary definitions focus on separating one’s self from people, organizations, or views with which one does not wish to associate.
