Back in the latter 80s, I was stationed in DC. The demonic activity in Washington DC was palpable--it was like entering a fog bank as you drove across the Beltway into the city. It was reflected in the people on the roads, on the streets.
This was when there was a person murdered every day (two on Saturdays) in the city, which, at only 700,000, isn't particularly huge. We lived on Bolling AFB, which is in the most crime-ridden section of the city. There was a military wife who was shot walking out of the Base Exchange (department store) by (determined ballistically) a stray round from a drug battle in a housing area overlooking the base half a mile away. I personally was mugged at gunpoint not far outside the gate twice in a 72-hour period.
This was also a period of time for a peak closeness to the Lord for my wife and I. If you read any of my testimonies of powerful spiritual experiences of many kinds in these forums, without a doubt it was while we were in DC.
I moved to DC having spent many years being oppressed by a demon. By "oppressed" I mean that a demon had been manipulating physical circumstances around me to keep me harassed and spiritually struggling. But during this period of time in DC, having experiences with the Lord such as I'd never had before, I became aware that I was being harassed and not just struggling with my own flesh.
That made me angry, and I finally one evening, standing at the sink of my bathroom, I invoked the name of the Lord: "I am saved by the blood of Jesus--let me go!" (My wife said she wondered who I was growling at.)
And that was that. It was like a glass rod breaking. It was as though I'd been bent over all my life and could suddenly stand erect.
That was a relief that went on, but a few weeks later I was asleep, peacefully. Then I heard a voice like a Basic Training drill sergeant at O-dark-thirty: "Ralph! Wake up! Now!"
I woke up and discerned in the darkness a figure of a person leaning over me. I wasn't alarmed, but surprised. When I raised up on an elbow, the person took a step back. I peered at it, trying to recognize who it was.
It appeared to be a woman, blonde, with long hair over the right front of her chest in a thick braid down to her waist. She wore black, like leather, with silver zippers.
As I stared at her face, at first she seemed to be lovely, but as I looked harder the flesh began to become translucent and began to reveal something ugly beneath.
At that point I realized, this was that demon, returning to check out the situation. I barked, "In the name of Jesus, get out!"
The figure took another step backward, then vanished.
I lay there on my elbow for a minute thinking what a wild dream that must have been. Then my wife touched me on the arm and said, "Did you hear that too?"
She said she had been awakened in the night by a sound like a swarm of metallic bees. She said the sound seemed to move around the room for a minute, then stopped, hovering over my head. She had been about to call on Jesus herself when she saw me lean up and heard do it--then the sound vanished.
