yes this sounds familiar. in my location no its not called dissociation, or dissociation related detachment. here where I am located being dazed and unresponsive is called catatonic. it sometimes happens with many mental disorders, and medications. if you go to a mental health unit you may see many people who are like this in the hallways or lounges.

here in my location we have many pschological terms for when someone purposely detaches like this sentence implies. here in my location we dont call this dissociation. we call this meditation, relaxation, yoga, and
dis - association (some people do not hyphen this word). here in my location there is a difference between dissociation and dis-association. here where I am the term dissociation is an unconscious reaction to a negative or positive trigger. where as the term dis-association means to purposely stop doing something (purposely stop working, purposely stop thoughts\thinking, purposely separate oneself from an activity...

an example of these things is

(medication, relaxation, yoga) I use relaxation visualizations to rest\relax\take a mental break from my life. I do this purposely for stress reduction/ relaxation. sometimes these mental breaks from my life include doing some stretching and other light exercises that help me to relax.

(dis-association) yesterday I was with my children in the shoe department. one of my children was getting frustrated because she could not have the pair of shoes she wanted. a temper tantrum was in the making. i purposely stopped my shopping, bent down on one knee and said how about we stop looking at the shoes and take these things in the cart to the check out. we can come back to the shoes after we take this cart full out to the car. when we got to the car I put on some childrens music for my daughter to calm down to while I loaded the purchases into the trunk of my wifes car. by the time I was done my daughter was calmed down and ready to continue shoe shopping. i averted disaster by purposely stopping (dis-associated) the shopping for that moment.

(dissociation) yesterday while shopping my child became frustrated. her beginning to temper tantrum was causing me to feel spaced out, and as if i was not completely in my body. this just happened to me, it wasnt something that I chose to do. trigger was the shopping plus a frustrated child. reaction was my brain made me feel my dissociation symptoms.

what do I think? well in my location when what you posted happens to me my treatment providers dont call it dissociation and dissociative detachment. they call it the above problem called dis-association, relaxation, meditation and my treatment providers do not see this as a problem because its with in my control to do it or not do it. when --I-- feel its getting out of control for me I take steps to stop doing it so much by recognizing when I am doing it and then getting physical again by taking a walk or doing some other physical activity.
