Do Humans turn into animals in after life?

Some views are:

*There are diverse traditions and beliefs on the afterworld and some consider the possibility of becoming an animal. Many traditions do not consider humans as a superior creature, they believe that there are some humans superiors to animals but also those who through their actions show to be inferior to animals. These are said to become the very animals they were cruel to for experiencing the pain they caused, or to become an animal with an special characteristic as i.e. a swan that has only one couple for life and when loosing it remains alone or perhaps an animal that is capable of sacrificing itself for the survival of their young or couple. Those traditions consider that an animal is just one more creature as man is and if there is something to learn, then a human can become an animal in a new life.

*At this time, there is no telling what really happens to us after we die. But according to some reincarnation beliefs, the only direction humans go is up. So, if we do in fact reincarnate, we would either become human again or something better.

*No, however, we do have, as spirit between times the capability of putting our attention into an animal. It is not uncommon for a recently departed entity to place their attention into another form such as a bird to get someone's attention. It is a way of saying goodbye. Those serving as guardian angels will do so whenever it serves the purpose.
