I'm type 2 and take insulin. I have had the same thing happen to me! Very nasty nightmares that I apparently talk in my sleep during and roll around the bed so much it wakes my husband up. I guess it is sort of good he wakes up because of it so he can get me to check my sugar or do it himself if he has to. I am usually in the 50's when this happens. Funny thing is, I am completely unaware of any hypoglycemia in the daytime and usually find out by accident while checking my sugar before a meal or something. And, just to be even more different, I have panic attack symptoms if I am much over 200 and get sort of mean- I am usually told by my family that I'm cranky and need to check my sugar lol!
