I can doze off, but it's the same as sleeping - absolutely nothing. It is a complete blank from the moment I fall asleep or doze off until I'm conscious again.

I can doze off, but it's the same as sleeping - absolutely nothing. It is a complete blank from the moment I fall asleep or doze off until I'm conscious again. I can't think of how it could be a disadvantage. I hear people have nightmares. I sure wouldn't want to experience those. I also have zero emotional response to music. All music could cease to exist and I would be completely unaffected. I've always wondered if there is some connection between not dreaming and not having any sort of emotional response to music. Are the two in the same part of the brain?
