Hypnagogia

Ever since I was little I used to have very wild hallucinations acompanied with often sleep walking. I used to share a room with my brother and he was so frustrated because of me. In the middle of the night I usually wake up screaming some weird stuff and pointing out things in the dark. One of the creepiest was when he saw me around 2 in the morning standing still infront of the window and mumbling at him: -Look brother, look, look! -What? -Right there points out in the dark don’t you see them? We never found out what it was, because he was so pissed at me, he told me to go back to sleep and that was that. One other time he again was awaken by my screams and fighting with something in the bed, screaming: "A SNAKE, A SNAKE, LOOK, A SNAKE." he was simply horrified.
