Truth_b - Thats very interesting about the study that your dad did, do you know if he did it independently or was it sanctioned in some way by the Watchtower? it seems that the WT was fully aware of the study either way. Do you know any more info on the situation or the report itself?
Biblewascreated - Good info on REM sleep and the effects on the mind. I personally believe in Fallen Angels, but in order for Demons to infiltrate dreams would imply, that they had the power to Read Minds.. UNLESS the person is already Posessed I suppose.
I believe that the Demon stories can be compared to the Stories, where people claim to have their prayers answered.. "I prayed for a new computer so that I could find a job working from home, and then I received a gift of $1250.00 THE EXACT AMOUNT that I needed, in order to buy the the newest Mac Book.. God answered my prayers!" Certain congregations and cultures are more infatuated with Demons, and it becomes a Confirmation Culture. "Sister-Jones said that a Demon was hiding in her closet, moving around her dresses.. Sure enough when I came home from meeting my clothes too were re- arranged."
So you have 4 factors at play :
1. MENTALLY Ill people are drawn to Cult Like Organizations.
2. Cult Like Organizations turn Mengally Stable people, into Mentally I'll people.
3. Fear Mongering in the Publications about Demons.
4. Confirmation Bias Influenced by the Groups Mentality.
There is another factor at play though, i speculate.
