I have read a bit of Robert Bruce's material including the most recent version of astral dynamics. I do not have a pdf version but rather two physical copies. I found it near impossible to find the new version in pdf form which led to me purchasing it a while back. In the book he talks about the mind split effect
Here is a few pages where Robert talks about it - https://taileaters.com/wp-content/uploads/2018/08/The-Afterlife-Experience-NEW-DAWN-ARTICLE.pdf
In short the theory is that you create a light copy of your conciseness and this is your astral body. Upon returning to the physical body whichever body experienced the most emotion tens to retain the memory. He also talks about there being a certain period where the astral body needs to re-enter the physical body and overwrite the memories in order for you to retain the information.
If someone experienced with astral projection could answer this to me I would appreciate it.
Also here's the book.
