In a dream, we travel along different lines of life, along our own or someone else's, we can be in a future that will not take place or in the past which did not exist, but at the same time it can be very similar to the real past. Also, we may not be in the first person, but in the role of the caretaker. An interesting fact is that if you look in the mirror in a dream, then most likely you will see yourself as you have never seen before, or you will see someone else altogether
