Does EVERYTHING have an opposite?

What is memory. For instance if the order of events were set in reverse, wouldn't the future influence the past as it pertains to the decision making agents who possess retrocausal perceptions of time. Do we have counterparts that do possess a retrocausal perception of time in the reverse order of events relative to our lives? Is their memory the reason why dreams sometimes come true?

This brings back memories of crazy discussions in college about dreams. Some classes started more discussions than others or was it more of, some profs more than others. Psychology classes had the most enthusiastic discussions, but they were never quite finished. I have even heard my mother and her friends discussing dreams. 🙂

to answer op, yes in real terms but no in imaginary terms.... hahahahhahahahhahahhaahhahhahhahhahahhahha
