Judith, I think you have a point. You noted that "degree of decoupling between experience and the attached emotions and memory" - it's dissociation, a survival tactic we all use, whether daydreaming in class or creating personalities and splinters to cope with emotional and phsycial overload.
And regarding positive thinking and imagining the future (using Law of Attraction), you're spot on. I remember as a child - and later as an adolescent - living with my abusive borderline mom, a bipolar who also had two distinct personalities unaware of each other. (My narcissist dad was mainly absent.) When I'd hear people encourage dreaming about the future, my inner response was bitter: "There's no point in imagining things that aren't going to happen. All that leads to is pain. It's better to have no expectations, 'cause you can't get disappointed." I was saturated with "learned helplessness" (as in Seligman's research).
