I will share my one encounter....
my wife and I fooled around a little before we were married. Not sex but crossed lines that jw's would certainly frown on. Shortly after we were married i experienced something i had never before known nor have felt in the 20+ years since....
we were living in our new apartment and i fell asleep, a bit anxiety ridden over our new marriage, bills i was unaccustomed to etc etc. i "awoke" in a sweat, an intense heat blazing through the apartment. I walked out of the bedroom and past the kitchen and heard the sound of a hot oven, that sort of 'whoosh' when the heat escapes. I looked over and the oven was growing a distorted metalic face. It looked at me and proclaimed in a voice that was (in my opinion) pure evil and menance:
"im going to tell everyone what you did"
i was terrified... Cold sweat instantly broke out all over my body.. And suddenly i realized: i didnt care.
I looked strait at the oven and said as much.
The face screamed and receded.
It was then that i genuinely woke. Sheets damp from my sweat but a true and deep calm pervading.
For years i really believed that was demon attack, that somehow i was open to it because of my wife and I's little dalliances. Eventually i realized the truth. I was young and stressed out over my new and difficult marriage. I was also deeply indoctrinated and feeling guilty over dating conduct that wasnt the least bit unusual even amongst witness couples.
A garden variety "night terror".
im not a believer in demons or the supernatural.
