Narcolepsy

I should warn you, I go to sleep I know you don't know what I mean Yet, I get upset or happy, I go to sleep You won't know when, I go to sleep 'Cause I'm not tired, I'm not tired I'm not tired, I'm not tired I know it seems that I don't care But something in me does, I swear I don't remember all last year I left you awake to cry the tears While I was dreaming Oh I'm drowning, save me, wake me up I should warn you, I go to sleep Nothing hurts when, I go to sleep 'Cause I'm not tired, I'm not tired I'm not tired, I'm not tired I'm not tired, I'm not tired I'm not tired, I'm not tired, I just sleep
