is this depersonalization? in some people yes in others no....

we cant tell you what this is with in you. only your treatment providers can tell you what this is with in you..

what I can tell you is what this is with in me....

the most frequent diagnosis in me for this is medication over dosage (as in my treatment providers got the wrong dosage and needed to readjust it)

at one point this was due to being in the same room as someone smoking pot..basically I was getting second hand high.

another time my treatment providers called it sleep deprivation because I wasnt getting enough sleep..

with in me its also been known as a nutritional problem associated with my eating disorder.

it is also part of my having multiple sclerosis, a physical health problem.

when it was accompanied by or rather preceeded by a trauma or trigger then it was called depersonalization example when I was abused I would dissociate (feel numb, blank minded) and when I found out the day my abuser was being released from prison I sat down and could not feel my body (numb) and was blank minded.

going numb and blank minded can also be a normal thing for example during meditation and yoga exercises the practice requires a person to let their self be calm, blank minded, and if anything does come into the stream of consciousness acknowledge it and then go back to being calm and clear minded.

some religious practices also require such things as allowing the body to go numb and blank minded.

in order for the problem to be ruled a dissociative disorder certain symptoms and criteria must be met...in other words other accompanying symptoms. here in america depersonalization isnt based on being blank minded and numb.

I dont know about in germany (where your profile says you are located) but here is what depersonalization is now here in america ...

Depersonalization/derealization Disorder 300.6 (F48.1)

A the presence of persistant or recurrent experiences of depersonalization, derealization or both:

1. Depersonalization: Experiences of unreality, detachment or being outside observer with respect to ones thoughts, feelings, sensations, body or actions (e.g perceptual alterations, distorted sense of time, unreal or absent self, emotional or physical numbing)

2. Derealization: experiences of unreality or detachment with respect to surroundings (e.g. individuals or objects are experienced as unreal dreamlike, foggy, lifeless or visually distorted)

B. During the depersonalization or derealization experiences, reality testing remains intact.

C. the symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

D. the disturbance is not attributable to the physiological effects of a substance (e.g. a drug of abuse, medication) or other medical condition. (e.g. Seizures)

E. The disturbance is not better explained by another mental disorder such as schizophrenia, panic disorder, major depressive disorder, acute stress disorder, post traumatic stress disorder or other dissociative disorder.

the DSM 5 also goes through the categories of diagnostic features, associated features supporting diagnosis, prevalence, development and course, Risk and Prognosis Factors, Cultural Related Diagnostic issues, Functional consequences of depersonalization/derealization disorder, differential diagnosis, and comorbidity.

Again only your treatment providers can say whether this is depersonalization with in you...

my suggestion is if this continues to bother consult with your treatment providers. they can help you discover what is going on with in you and help you figure out if this is normal, a medical problem or a mental disorder.
