Imagine being a spirit who graduates from this Premonition Timeline to the next timeline. While alive here, you would occasionally astral project in your sleep. During one of your ventures onto the astral-scape, you meet your own spirit from the future timeline. Imagine accidentally going back to the wrong timeline to the wrong body the first time you met. Imagine then being able to do this regularly. If you can imagine this, then you can imagine what has actually been happening to at least one person in this timeline. This story is loosely based on this entity.
