I love mystery and unexplainable, how many crazy things happening around us and sometimes we just too much in a hurry that we do not think about that. Like your story and it made me shiver, when I imagined that such situation could be a truth that someone could have such lively vision and see a person even talk but nobody else could see that person. Many people may think they went crazy. Interestingly written, intriguing, leaves all options open for further thoughts and ideas. Great!
