Certainly a religiously coloured description which contains also truth of course. For me this view contains too much 'automatism'. You do not reincarnate automatically and do not die an astral death as such but you leave it behind permanently instead, but not necessarily to re-incarnate. You can also go higher or be helped ('retrieved' by helpers) first. And then go on according to your state of being.
According to Monroe's research and system, many humans end up in astral realms and (a bit higher in) Belief System 'Territories' of certain religions or after-death beliefs they held. But the do not 'die' there to reincarnate. That seems nonsense to me. Reincarnation is a voluntary thing. Instead they can dwell for eons there if they do not wake up realizing they are in so-called 'hollow heavens' (as William Buhlman calls them) or false and in part self-created hells.
Further up, there is a relatively 'free' area called Focus 27 / The Park. But it is still 'human' in a way and reincarnation 'can' take place from there it seems, or at least the preparations, but as said, they are voluntary. The Higher Self is higher, as is Source. You can re-join it. I hope I will but am not sure.
Here's the research and the focus levels again:
A simple system of labels (called Focus Levels) devised by The Monroe Institute to indicate various states or phases of consciousness.

William Buhlman recommends demanding "Higher Self Now" at the point of death. Or maybe to directly demand the "Source" reconnection. Seems a good strategy. You could even not go to the 'school' of rebirth and Focus 27 then. However I believe in Focus 27 you are free enough to decide if you want to go again or not. But we cannot be sure of course.
Michael Newton also has a lot on it and desribed the process with Earth as a school for souls to reincarnate. He did not see further though (not ET lives, not Higher Self). These preparations also seemed to take place in/with Focus 27. Again, I think if you are 'evolved' enough you have free will and there is no automatism and you can go 'anywhere'. Even re-join Source and maybe do sth else then from there.
The advice of keeping detachment and looking on your life like a movie of s.o. else is a good one. Detachment from this life helps also to let go of attachments from the past life.
I do not believe in karma-automatism though. It seems outdated. If you know you can be FREE then you are already a step ahead. The problem is that many people who grew up with religions are trapped somehow and thus 'bound' to go into the 'light' that will lead them to a BST of their vibrational state. Nothing wrong with that, they can be happy there. But they will not move on for quite a while. I want to avoid that for sure.
