Hello Micko! And All! This is a very touchy subject. All if anything that is written would be written only from past experience or by some Psychiatrist that may think he/she knows it all. Anyway, here is may past experience. i, for a period of time lived with my Grandmother and my cousin, to wich my Grandmother adopted when she was 4 years old because her mother, my aunt was a paranoid pscizophrenic. My cuz and I slept in bedrooms that were beside each other. Almost every night we would project together. It was rather cool. As time went on my cuz, God bless her soul, became more and more like her mother. She eventually started to hear voices too. I can distinctly remember one of the last times we projected together. It was awful. She was screaming for something or somebody to leave her alone. Then I kept being pulled to her room. I had a bad feeling and tried to fight it, but I couldn't. Finally she won. My spirit was pulled into her room at her bedside. She said to me in a very stern voice "Will you take these demons over me?" Then i woke up! Talk about a frightening experience! I could never talk to her again about the fun we had. She was now under Doctors care for her newly found disease. In a way I think it was because she opened a door that she was not able to handle. I still pray for her every day. So, when you ask if AP can be linked to mental illness, I believe "YES". If a person is not strong enough to deal with these new doors and windows being open to them then it is possible for them to "Go nuts".
