I've always dreamed that I have a sister, only I don't actually have a sister. Interestingly she is actually a more commonly reoccurring dream character than my brother is. When I was younger, I just called her the mystery girl, because I never had any idea who she was, but in the dream world I never questioned her existence at all, and it always just felt like I knew her. One night in a dream while talking to her, I just simply called her sister, and after I woke up, it made sense, in the dream world, she did feel like a sister. Also interestingly she and my grandpa have always seemed to be the most common dream characters to appear in my dream, both before and after my grandpa died. Still, it doesn't seem that strange that I can still dream about my grandpa frequently, I mean I do have a lot of memories of the man, but my sister, I've never even seen her, so how can that happen? Has anyone ever heard of this before?

Also, interestingly, in most dreams she appears in, she is helping me to figure out something, or to solve some problem. She has even sacrificed herself for me on a few of occasions, and I have done the same for her, but not as often. And by sacrifice, I don't mean death either, mostly its just getting trapped in some unfortunate circumstance that seems inescapable, although she always shows up again down the road. These dreams also tend to be the ones that stick out more to me, and are usually more vibrant than others. She appears in a few of my more dull dreams as well, but usually if she shows up in a dream, it ends up being a doozy.
