Yep, I have this all the time too. Probably the most direct and noticeable symptom I have. Is it a part of DPDR? Who knows, really. DPDR is kind of an umbrella term, it seems. Like anxiety and depression, a comprehensive list of “symptoms” of DP would probably include just about any weird feeling you could imagine. But if this one issue went away I would probably be able to lead a halfway normal life. If you are asking for advice on how to ameliorate it, well, I would love to hear what others might have to say, cause I’m fresh out of ideas.
