hi Lea, if I may attempt a little interpret...
it suggests that you are going to "blow up something, like to make it a bigger problem than what it really is"
and I do this too sometimes...maybe too much worry about something. then the next day, you find out, wow, I did all that head trip for nothing, as it turns out, it didn't hurt me at all what I was thinking about. then the doctor in the dream, he acts as a guide, to tell you a message. so he may be a real guide, slipped into your dream to disengage your worry.
have you discovered something you are worried about concerning perhaps a biting remark somebody made to you?
