I've read 7 of the books on your list....
Another one to explore is '
Life In The World Unseen' (Anthony Borgia), whether true or not, it's still a very entertaining read and really stimulates the mind.....
There is A LOT of intriguing information found on the website for the Multidimensional Man... Really good write-ups there... Found the website to be a lot better than the book....
I really enjoyed the William Buhlman book (Adventures In The Afterlife) and there is a lot of excellent insights in Pim Van Lommel's NDE book....
Have fun Seeking/Exploring Metal68!
