what is dissociation? lately i've been having this feeling of "waking up" and suddenly realizing i'm somewhere. like all of a sudden i'm at the gym on the treadmill, and i think, "how did i get here?!" also, i feel like i'm in a dream sometimes. like my therapist is talking and i'm trying to focus on her and it feels like she's not real. are these two examples: dissociation? or if not, can anyone tell me what they are?
