The pons sends signals to the thalamus and to the cerebral cortex, which is responsible for most thought processes. It also sends signals to turn off motor neurons in the spinal cord, causing temporary paralysis and so preventing us from acting upon our dreams http://www.dailymail.co.uk/health/article-90598/What-happens-body-youre-asleep.html http://www.dailymail.co.uk/health/article-90598/What-happens... Something is affecting this part of your sleep cycle. I have dealt with this for years and finally found that if I go to sleep hungry my stomach signals short circuits the process and the brain never send the signals to my spinal cord to shut my muscles down. The weird part is because the spin is sending signals back to the brain, the brain does not recognize anything you do as unusual so you can be screaming and not wake yourself up. Generally the only thing that will wake you is someone asking you a logical question (like your dad did) which activates other parts of your brain and induces at least semi-consciousness. I have woke up, sitting at stop lights in my car 5 miles from my home. It is a scary and dangerous disorder. Sleep walkers have a propensity to turn extremely violent when physically touched. A good portion of sleep walkers experience symptoms when under stress or agitation so generally your mental state while asleep is aggressive in nature. There have been cases of sleep walkers attacking and killing people. This is a very serious condition. You need to tell everyone in the house to never touch you after they have seen you go to bed and to always address you before approaching you after seeing you go to bed. Even in the morning at a time when you would be waking up. Tell them to speak softly and calmly to you and to always maintain at least 15 feet between you and them, while they ask you logical questions. They should ask you items like, what are you doing? where are we at? what is 5 + 5? why is that elephant standing on that zebra? They should go in that order, the more illogical ones will cause you mind to work harder to parse, but can cause aggravation if asked first? You are a real threat to yourself and others you need to find a sleep pathologist ASAP.
