After reading the responses, I am feeling a bit foolish myself. When I first read the original post, I thought the poster was asking if it is okay to dissociate in the presence of a person and, if so, what rules might be in place to determine around whom one can dissociate.
However, I have to admit, I am just beginning to learn about dissociation and how it pertains to me specifically. After experiencing some seizures about a year ago, only to find that they were dissociative events (non-epileptic seizures), I have been painstakingly working at understanding how I dissociate, how best to ground myself, and how to stop dissociating. Good luck in your research!
