I know the "animal souls" question was for Perry, but I wonder about that as well. I know that Science shows zero evidence for a soul that lives on, but who knows?
Well, I for one can testify that after I was saved, my mom's distant cousin told me that i should pray for the baptism of the Holy Spirit. Not thinkng much of it, I prayed for that one time only. About a week later, I started speaking in tongues all night long while my soul was separated from my body, presumably in heaven.
I had the amazing experience of actually being in two places at the same time. I did not however have two consciousnesses. But I could choose the consciousness to be in the body at home, or in the spirit in heaven.
This went on for several days. I would wake up fully at peace, but tired in my spirit. My wife witnesses the speaking in tongues, so I know it wasn't a dream. It was definitely no dream.
You should read up on terminal lucidity, where people, sometimes with their entire brains eaten away with cancer or Alzheimers have a few minutes of complete lucidity a few hours before their death. I believe that to be the soul speaking when it nears departure.
My mother did not have an easy passing recently. I was told that a few hours before her death, with 4 times the medication needed to knock anyone out, that she would have episodes of panic and cry out, " I don't want to die"! She screamed out other things as well. I believe that was her soul expressing it's uncertain destination.
People do not have to be uncertain. God promises KNOWING to his children. I have personally experienced the cocky self assuredness as a fully engaged Watchtower representative, and the KNOWING that God puts into a person supernaturally when they a born again. They are completely different.
