I believe that these experiences are real...that you do feel pain that you do "see" things. I also know that the mind is a VERY powerful thing and can manifest some incredibly horrible things, terrifying, paralyzing things that CAN and DO cause pain to the body. But if you only attribute their existence to demons and not to some physical cause, say multiple schlerosis or lupus or bipolar disorder, and arent interested in actually finding out what they REALLY might be...then you will get responses such as MD's which frankly reflected what I was thinking.
In fact, not even two weeks ago, I was half awake, you know that dream state where you believe 100% that what is happening around you is actually happening its so real..and I saw my eldest son sitting on the edge of my bed. He was asking me something and was getting irritated that I wasnt answering him. But I COULDNT MOVE. I was paralyzed. My eyes were looking at "him" in silhouette there, and every effort I could muster up failed to move my arms, my legs, my head..even my lips to reply. I screamed behind my closed mouth so loud that I woke myself up. My heart was racing, my son was not there (he was sleeping, I checked) and my arms were asleep from having them under me in my sleep. My calves were cramping from the kicking I had been doing. I never attributed this to any demons. As a JW I probably would have gone right TO that conclusion...as they are so paranoid of demons as to see them EVERYWHERE like dust motes. I have often woken up after having been dreaming of drowning, feeling myself under the water, unable to breath...but things like sleep apnea can DO that to you. As can stress and spicy foods.
If demons were going to attack people who are DEPRESSED, shit the entire organization would be attacked 24-7. If they were going to hone in on people who were "spiritually weak" again...the entire congregation would be attacked mercilessly because the standards for "spirituality" cant be MET that are set in that Org. The bar is perpectually higher than attainable...like living up to the law covenant. So you are NOT CAUSING THIS to happen to you by doing or not doing something to please God. Cripes..thats just rude to even imply to you.
God doesnt punish people like some cruel prison guard, constantly giving and taking back and punishing people, holding the demons back then releasing them on people. What kind of freakin GOD is THAT? I know that that is how the JWs treat people. Constantly threatening them if they dont do do do do for Mommy Dearest in Brooklyn.
Now THEY are some scary shit. Get to a doctor, in fact several doctors, both physical and mental and get some real answers. At least elminate those possibilities. If you now have a child and you have some mental disorder that is inherited, you owe it to that child to get it diagnosed now. My mother in law just found out at age 57 that she is bipolar. She now realizes that her father, and at least three of her children are bipolar as well. But they have all been too proud to go to a doctor and didnt WANT to know there was something wrong, but TREATABLE going on there.
If you really want to know the WHY in all this...you need to step out of the box you have created for yourself...and look beyond the paranormal to the NORMAL for some answers.
