Have you ever had a bad dream that was bad only because it challenged your intellect and overloaded your mind?

I have "smart dreams" all the time. I think a lot. I have found myself working calculus problems, physics problems in my sleep. I have found myself creating incredibly difficult algorithms to solve riddles that I couldnt solve consciously. I have found myself discovering spiritual and philosophical truths that I wake from and write huge discourses about. Sometimes I get overwhelmed in my sleep and it scares me awake. I often wake up with headaches constantly because, even though Im asleep, my brain refuses to shut off and take a rest. I get headaches if I dont think enough and dont challenge my intellect enough. Is anyone else like this?
