I wonder if someone can shed some light on this: For the last several years, almost every night, I wake up from a dead sleep with an adrenalin rush. feels like my heart sinking and anxiety. sometimes it nearly knocks me out of bed. I have found myself walking very quickly through the house for no reason at all. I am not sleepwalking. I am very much awake and usually find somthing to worry about right away which keeps me up for 2 hours usually. Then, about 5:30 this relaxing feeling comes over me and I quite happily go back to bed and to sleep. Also, at night, problems that wouldnt bother me much during the day will bother me "unrealisticly" in the middle of the night. Why should I feel diffrently about a subject at night than during the day?
