I rarely dream about students or clients. I have had the not being able to find my classroom dreams in the fall as school starts and I can still have the failed the bar dreams years after I passed them all.(I do not plan on ever taking another bar exam). But I cannot recall dreaming about students in general or any of them specifically or clients either. I dream about my job but not in relation to the students or clients.
But in my therapy dreams, the therapist does not specifically show up either. When I have therapy dreams, the therapist is either missing for some reason or not the right one - which we discover in the dream together - that I am not the right client even after we have been meeting for an hour or so.
