I was speaking with a long-term client recently with whom I have a solid therapeutic relationship, and in the middle of session he reported suddenly feeling totally disconnected from me.  Now I’m a pretty good therapist, but I’m not above being occasionally distant or making a mistake, so I didn’t take it as a serious problem, but I did start exploring the experience with them.  And after a few minutes of talking around the edges of it, my client says something like “it just didn't feel like I was talking to a real person for a second there, it felt like when I talk to AI.”
