as caused by the lingering dead. a review by sean casteel at ufodigest of a reprint of carl wicklands book "thirty years among the dead" by the author-bibliopole timothy e beckley.
the author explains the techniques he and his wife, a spiritmedium, used to cure some of the psychiatric patients under his care, describes the phenomena of possesion by dead souls, and gives some advice on what to do and not do when these phenomena appear.
another review of the book can be read at michael prescotts typepad blog.
what is of interest is how the phenomena wickland describes match descriptions of phenomena attributed by some researchers to aliens and agents other than the suffering deluded souls of the dead but not yet departed.
some or all of the book can be read at new-birth.net.
