No one has ever died as a result of being hypnotized.
Did the author even researched about Age Regression-Hypnosis?
This is how I wished the movie had been. During the second half, there should've been a mystery if Ivy was the reincarnation of Audrey Rose and in the last scene you find out the truth. If the hypnotist was able to bring Ivy back beyond her birth, it would supposedly prove that she was Audrey Rose in a previous life. She wouldn't have to die for this to be proved.
It really bothered me how the author described Audrey in the last chapters of the novel, as if she were an evil spirit possessing Ivy's body. Totally absurd
if you believe in reincarnation. And the whole thing about Audrey's soul returning to soon, trying to kill Ivy, seeking to escape this earth life was ridiculous. Not once did the author lead the reader toward a suspension of disbelief. I wish someone could rewrite this incredible story in a different perspective.
