Yes, sometimes I have felt a discomfort that I did not recognise until after the session. And each time this was my reaction to the T.

Once T moved close to me to demonstrate mindfulness using my coffee cup, and when I asked the next session if it was deliberate move of entering my space, he said no, and after that was VERY careful about moving around my comfort zone.

In my opinion if the T said yes he was testing my boundries without my consent it would be a cruel gesture. We deserve to be treated as a person.

If there is a mistake, that felt like a mistake, it is up to us to communicate what we feel.

My understanding of a healing relationship is that the T shows unconditional positive regard, or love in the spiritual sense. And we grow by being in a place of acceptance, as the T and client are equal with different roles.
Any pain we feel is worth noting and discussing. Assume the T does not read minds, or wishes to guess what you are feeling. We would not get better if T's told us what we were feeling.

All the best
