Yep! I've had personal experiences with this realm.
Not so much now, but at night, I used to have experiences where something was holding me down. I couldn't move or talk. When I finally managed to yell out, “In Jesus' name. . .” is when “it” would disappear.
I told my friend about the incident and she said, she's never had any similar experiences, but she knew someone who did and she said it had something to do with the spirits of Incubus and Succubus.
Then there was another experience when I was renting out a room with this lady and wasn't home at the time. The lady said her dog started barking and backing up down the hallway as if someone was coming in. She thought it was me, but when she looked out into the hallway and into my room, no one was there.
And I also mentioned this incident to another lady who was renting a room at the time – also a Christian – and told her how scared I was, she got SO mad for letting that fear overwhelm me. She told me that I should end all of my prayers with, “In Jesus' name.”
There's authority and power in the name of Jesus. EVERY KNEE bows and WILL bow to Him!!! I never knew that was such important thing to do, but was the best thing I've ever heard in my life!!! It was such a comforting thing to know!
But, it's a realm that's very real, though, and I try cover myself with prayer every day. I also have a prayer book called, “Prayers That Rout Demons” by John Eckhardt.
