Hi, ------- There is a desease that makes the person need to sleep when it's getting dark. I met a person like that who could easily fall in deep sleep even when he walked (with 60 lb on his back).... He never saw a movie cause he allways falls asleep as the lights go off....) That person was released from the army after this desease was identified. Please make sure you don't have the same desease (or similar). -------- Best regards,
