My youngest daughter has slept walked since she was old enough to walk. She is 10 years old and still does. She looks like she is awake, but the lights are not really on, she will respond, but again she is like the HAL 9000 with have of the memory sticks pulled

The is another sleep issue I refer to as the the "Slide Show". Often when I have a lot on my mind, but I'll lay down and close my eyes then the show begins. Flashes of everything I can think of. I feel like I never really go to sleep. It can last for hours or most of the night. I'll toss and turn the entire time. This was also an ADD trait that I learned about with my ADD dx in 2009. After I began my Adderall treatment sleeping for the most part is Much Better. I can make due on 4-6 hours sleep better than I used to on 8 or 9 hours.

If you are having trouble sleeping, definitely go talk to a doctor about it.
Good luck
