Here I genuinely suggest an improvement upon the quoted form of expression in what I hope is an agreeable manner.*

I'm not sure what you describe as a body/mind dichotomy really makes sense or is the proper way of describing your experiences.

A better way to express this sentiment, without demeaning another's experience:

• "What you describe as a body/mind dichotomy doesn't really make sense to me. [Explain why.] It reminded me of the neo-Freudian concept of egodystonicity - does this theory fit your experience?"

*I only just noticed some may have been reading a negative affect into the above which I have hopefully now meliorated.
