I had night terrors growing up and was a sleep walker. However, I no longer wake up screaming. Instead, I jump out of bed and run around the house looking for who knows what until I realize what happened. These have happened in the past and I just got over it, but it would cause me to stay awake the rest of the night feeling the worst kind of depressed feelings following an episode. However, now, I am usually okay within an hour and can get back to sleep, unless it happens in the morning a couple of hours before waking. In that case, I end up getting up for the day.
