Hi Matt!
As I understand from your question, you are only getting these Migraines while sleeping and you've never had a Migraine while awake?
I just want to make sure I got that right....
The only advise I can give you is to talk with your doctor. Something like this needs to be discussed, especially if you have paralysis type symptoms going on.
We have a list of Migraine and Headache Specialists here on the site that may help you find someone.
Good Luck!
