Almost Killed my right hand

I also paralysed my right forearm during sleep this morning! My brain was giving up some kind of subtle signals, conjuring heart-racing type of nightmares. I dreamt that my sister and I were holidaying at this old house, where there are shuttle buses to her classes. But strange things came happening, like how the clothes will multiply and my blazers got dyed...*brr..* So when I gain consciousness, I realised I had my arm in an awkward position, one where my right arm is wrapped over my torso and underneath my left shoulder. As I freed my arm, I could feel the tingling sense of touch returning, the gush of blood through my fingers. I wonder how long have I slept that way and what if I woke up with a paralyzed right arm. Scary chinese new year second day morning...
