I'm sorry. I know how distressing those dreams are. I get dreams about treatment/therapy/the hospital all the time. The last time that I was in the hospital, every single night I would get horrifying dreams about returning back to school.

These dreams sound like your innermost emotions trying to express themselves and be heard. Your psyche is trying to work through these strong feelings that you have towards this issue. Have you tried talking to your T about the dreams? That might be helpful to be able to try and work through some of the odd details that might somehow be significant to you in some way.
I'm sorry that this is so frustrating for you right now. But it won't be like this forever. So hang in there, mija!
