I believe people with DP/DR experience ego death.
There always seems to be some underlying anxiety, and I often wonder why I am so anxious. I know I am anxious... but of what?
It's as though I have a 'fear to exist'.
I believe the notion of having a fear to exist is the result of unresolved ego death. Basically, this fear should diminish once we have truly accepted and come to terms with living life through an objective lense....without an ego.
TL;DR: I feel as though underlying anxiety that comes with DP/DR (aka the fear to exist) is a result of unresolved/unprocessed ego death.
Ego death is a "complete loss of subjective self-identity." The term is used in various intertwined contexts, with related meanings. In Jungian psychology the synonymous term psychic death is used, which refers to a fundamental transformation of the psyche.
I've heard so many stories of people experiencing drug-induced ego death, where they feel like they have died and then become extremely anxious, and I realize this is the same phenomenon that those with DP/DR experience. We may not feel 'dead' per say, but it feels as though a part of our psyche is missing and we are left feeling anxious.
I hope this makes sense, and I wasn't too vague.
