I had been going to Rocky Horror for well over a year and had become
rather well known to both the crowd who went in to see the movie as 
wellas the crowd of people who'd hang in the parking lot while the 
movie was playing. I'd had many interesting conversations with people 
and my views on the metaphysical and the surreal were well known to some... 
One night while hanging out in the parking lot a friend of mine named
Freya found me and asked me to come talk to some people about something
she thought I might have an idea about. She led me over to a group of 
teenagers sitting huddled together under a streetlight. I've never seen 
such a frightened group of people before in my life. During the next half 
hour a story about black magic, summonings, incomplete rituals and 
subsequent weird goings on evolved. One girl even had three very long, 
you'd have to call them claw marks, going from one shoulder to the 
opposite hip. These kids were totally terrified. As we were talking to 
suddenly you could feel the temperature drop, the hairs on the back of my 
next stood up. Freya nudged me and looked towards the sky where some huge 
black shape was rearing up from behind the building into the sky. Several 
of the kids started to panic. The girl with the claw marks was screaming 
"It's back! It's back!" So I shouted, and thought and emoted and 
challenged "Try taking on someone who knows what they're doing and isn't 
afraid of you!" and with that, the shape fell apart like a cloud in a 
stiff breeze (of which there weren't any that night).
An hour or so later the show let out. We hung out in the parking lot for a 
while and then as we usually did we went to some diner to get some 
breakfast. I don't know what time it was when I got dropped off at my 
apartment, it had to be rather late (or early for that matter) the matter 
in the parking lot was forgotten and I crawled into bed to get some sleep. 
A little while later I noticed something odd. There was a main road that 
had heavy traffic on it 24/7 just down the way from our place and the 
white noise of the trucks and cars going by often lulled me to sleep. I no 
longer could hear the traffic noises. I then noticed that the fish tank at 
the other end of my bed which had been gurgling happily for months also 
wasn't making any noise. I tried snapping my fingers and though I could 
feel them snapping, I couldn't hear a thing. Nervous I rolled over and 
reached to turn on the light, or I tried to. All of a sudden I was frozen 
in place, I couldn't move a muscle. I then became aware of a presence or 
more than one in the room with me, they were talking, the first sounds I 
could hear. What language they were speaking I have no idea but there were 
three separate and distinct voices two of which sounded male and one 
vaguely female. Their voices sounded both as if they were right next to my 
ear and coming from a million miles away. As their 'discussion' continued 
it changed and sounded as if they were arguing and I somehow knew they 
were arguing about me. I thought as hard as I could "Get out! Get out! You 
have no power over me!" Suddenly, it felt as if one of the beings came 
rushing towards me and the female of the voices said, in quite clear but 
totally flat and emotionless English, "I only speak in blood." At the same 
time it sounded as if my bass guitar had be flung off it's stand onto the 
floor. The sound of a lamp shattering was heard. The floor from one end of 
the house to the other creaked as if a gigantic weight had been dragged 
across it. It was then I also noticed I could move again and the normal 
sounds of traffic and fish tank had returned. I sat up and flipped on the 
light expecting to see my room in ruins and found that everything was in 
it's place and nothing had been broken. Moments later my roommate who was 
as into psychic phenomena as I am was standing in my doorway asking "Just 
what the FUCK was that?"

I never heard those voices again. I never again felt the mysterious loss 
of sound and paralyzation. And to this day I have no idea what "I only 
speak in blood." means or why I was told it.
