So, for interest's sake...I came up with the concept of Vander's dream yesterday evening, and was tweaking it in my head for a good part of the evening. So, of course, when I went to sleep myself, I managed to roll over in a way that completely cut off circulation to my left arm.
Woke up at about 5:30am with absolutely no feeling in my arm. I woke up, after thinking about writing a character to believe they had no hands, and felt like I had no arm myself. You can imagine how confused my brain was for a moment. XD
