On a few ocassions I "blacked out" for a few seconds in the middle of my daily routine. In one instance I was at work, and for a few seconds I have no memory of what I was thinking about or what I did.
Now here is where demons are scary to me. You have had unexplained blackouts, but instead of consulting a doctor, you suspect demons. Now that is dangerous! You may have a serious medical condition!
Also at night, I frequently couldn't sleep. Both myself and my wife kept waking up cause we heard noises. Also I began experiencing hypnopompia/hypnogogia on a regular basis.
Hypnopompia is frequently blamed on demons. I heard many stories while in the dubs that all had similar themes. I didn't believe all of them because they were usually told and retold so you can be sure that they were "enhanced". but I had a dear friend who had an experience like that, and so I was certain of the details. Her experience was horrifying, and we were both certain it was demons. But now I know their is a medical explanation for it, and it is common.
One night my wife and I were lying in bed, wide awake and we heard the voice of our child right next to us in bed. Except our child was sleeping in her room. That freaked me out a bit because we were both wide awake and we both heard the same thing. And my wife who is still a JW has never done hypnosis.
I have no explanation for this. Maybe you and your wife were both in a semi conscienceness state. And your daughter in the next room called out in her sleep. Being parents, you heard this call distinctly and close by. Just a guess.
BTW when I vacuum, I frequently hear my children calling me. This would really scare me when I was a JW, and boy did I pray a lot over it! But I think it's a parent thing, no matter what you are doing, you always have one ear cocked listening for the kids. And since vacuuming can drown out a lot of noise, I'm listening so hard that I can actually hear it, even if my kids aren't vocalizing it. Either that or every vacuum cleaner I have owned for the past 25 years has been demonized. Or maybe I'm demonized but the only way the demons can reach me is through my vacuum cleaner. And they just love yelling "Mommm", and watching me switch off the machine and yell "wha-at".
