I've done a few of the above too. I have serious arguments with random people in my sleep, i shout out, and cry sometimes, obviously so much so that my eyes are puffy and sore in the morning. I remember sometimes also trying to look for things in the night, whilst i'm asleep, and wake up whilst looking for whatever it is i thought was trying to get me, or a noise i could hear in a dream . I used to sleep walk when i lived at home, my parents would come downstairs to find me just sat in the chair, looking straight through them, for hours on end, then i'd just get up and go back to bed! Very strange
