What do you mean by "related" (english is not my mother tongue).
I can understand he is stressed, working fulltime as an occupational therapist. Probably a lot could be done here - is it something I could work further on?
---
Can not see any other reason to why he is stressed, but I will discuss it with him.
What about that "nightmare"-thing? .. He also told me he sleeps better in the afternoon (after dinner) than at night. He usually doesnt sleep after dinner.
