I have SLE yesterday I felt my eyes rolling back in my sleep. I couldn't wake my self I ended up with a migraine later. Could this be a seizure?

Possibly. See a one of your physicians for a referral to neurologist they can work together with to coordinate your treatment. SLE is best handled as a team challenge and by providing good info and complying w/ recommendations - you're a member. SLE can be tricky, but it can be tamed sometimes. I wish you well!
