I think you may have a predisposition to "de-personalize" in times of high anxiety,
but it is not consistent/persistent enough to warrant some kind of disorder. What you desribe sounds like more of a defense-mechanism against the level of stress you may be going through
at the time.
However if this becomes more of a problem for you, please do check in with your Dr. or therapist.
Kindly,
