Okay Wandering soul... There's also a book called, the great simulator, by david mccready, I read it couple of years back ... Might give u a sense as why some people have this type of disconnecting moments or experiences. I don't know much about dissociation in terms of mental illnesses, but few people have mentioned and described their experience. And it actually blows my mind. Am definitely looking into this area. But ya, most people that have these disillusioned moment, often become seekers of truth and spiritual wholeness.
