This is not new, the soul being a prison for the true self (spirit) is old gnosticism. The chakra system, which is the fabric of the soul, is ruled by the saturn-moon matrix.
Many authors discuss this in their books, including D.Icke, G.Kavassilas, R.Monroe, MN, WP, etc.
According to Monroe, after leaving the physical body, he also had to leave his second heavy and dumb body in order to travel beyond...
So, no surprise that the next step to escape this nested/layered prison would be getting rid of the soul, the soul's death. And who knows how many layers there are afterwards.
The afterlife matrix is as solid and artificial as this "physical" reality.
Oh, and the religious brazilian movie you are talking about is called "Nosso Lar". I found it in HD 1080p in PB. It's funny how many people find the recycling center presented in this movie so fkn beautiful.
