Hey Hun, dissociation is a spectrum, not confined to just one exact definition (DSM-5 is the final ultimate say for DID) but it spreads out from there. Everybody dissociates at one time or another, depersonalization, derealization, PTSD. Even borderline personality disorder has others also.
Also getting stoned and doped up produces like symptoms of self doubt. We couldn't diagnose you, but it does suck at being confused. Do you have a specialist to communicate to? Only they can help sort your concerns out.
Feel free to keep expressing because I don't know, I'm like you, another person on here looking for support in this crazy world of MI.
