I don't know if it'll help you, but I envision myself as having two mes: Sleep Me and Awake Me. Sleep Me is an asshole who'll ruin my life just to stay asleep for as long as possible. He fights tooth and nail to keep Awake Me from taking control of my body. ”I'm gonna go back to sleep" is Sleep You talking. They're trying their hardest to convince Awake You that you can't possibly stand up until Sleep You has had their fill of sleep, but it's not like "just be happy" or "just pay attention–" you can control your legs!
