I would work on writing the story to get your mind off whether he has answered you yet; you can't email what you don't have anyway? But it could be that writing the story will help with the nightmares too; often when we "pay attention" to them and work with them in any form, they lighten up because you are paying attention and trying to understand what they have to say and that's enough for them, their "message" of "Pay attention!" is done.

You aren't on any meds that have a side effect of vivid dreams are you? There are several and moderating those could help too if you have a pdoc, discussing that you have nightmares all the time could be solved by him without discussing the topic(s)?
