A reader makes contact with whatever was breathing in his room
I found it incredibly interesting just how similar of an experience you have had to one I have had myself. My name is Derick and I am currently a 24 year old biology graduate. In the summer of 2006 I was home for my sophomore-junior summer break when I encountered a breathing, like the one you have described.
I was bored one night, and when I get bored I tend to come up with different "experiements" to play with. As paranormal activity happens to be a subject which I am rather fond of, these "experiments" often involve things of a spiritual nature. I feel kind of foolish recounting this story now, but I am going to chock it up to a stroke of childishness.
I looked up a technique for summoning demons. I found one technique, which to me was much more plausible than all the circle drawing, candle lighting, and chanting that I usually see on the web. The technique involved essentially focusing on one type of feeling that one felt could channel a demon. I chose hostility, because it was the feeling I had most readily available at the moment. So I played at that hostility meditation for about half an hour before I decided it was enough. I went through the rest of the night normally.
A couple of hours after the meditation, I got ready for bed, which involved putting on an eyemask with built-in headphone so I could listen to my mp3 player while I went to sleep. I was lying there for a few songs and nothing was out of the ordinary. I do rip most of my music from online, so there are frequently long pauses between songs. The third or fourth song included one of these pauses. During the silence I heard what sounded like very heavy, very deliberate, labored breathing coming from behind my headboard. At first I thought it was just part of the music, so I unplugged the audio jack from the player. I could still hear the breathing, but I thought it was just my own breathing that I was hearing, so I lifted the mask from my eyes and looked around, but there was nothing there. So I put the mask and music back on and lay back down.
A couple more songs went by before a softer one came on. Over the soft music I could hear the breathing again and then what sounded like a low growl. I took the mask off completely this time and put it aside. I could still hear the breathing coming from the narrow space behind my headboard, but I was too afraid to look. The breathing started to get more and more gruff; it sounded angry. I got the impression that it was working itself up.
Unexpectedly, I felt what I can only describe as a very large, very strong hand come down against the back of my neck, pinning me to my bed. It was a very hot touch and it felt very viscous, for a lack of better word, like it was holding me down under liquid. The heat spread rather quickly down the core of my body; I could feel it running down my spine. I was utterly terrified, until I felt it reach the bottom of my spine. Then something kicked in, maybe an instinctual response; it just felt like something bad would happen if I didn't do something. I got the notion that whatever it was was mocking me.
After that I was no longer scared. I can even remember laughing, or trying to laugh; it came out more like a cough. But somehow it changed me so that it made me actually enjoy it. I loved how strong it was. It made me want to fight back, so I reached up at the air and grabbed what I imagined to be its throat. I could tell that I wasn't making any ground, but it didn't bother me. Soon after I started fighting back, I lost consciousness. I didn't wake up until 1 or 2 that afternoon, which was extremely late for me, but other than the tardiness I woke up completely normal.
Some events and feelings afterward seemed to validate the experience for myself, but I feel as if the nature of those experiences would undermine any credibility I have left. It is important to note though that those events culminated in a situation where I felt it necessary to pray to God for help, and then they immediately stopped. I have often considered submitting this story to the Your True Tales section of this site, but I could never get over the embarrassing nature of my story. Furthermore, I didn't really feel as if it would be at all pertinent to anyone else.
I find it interesting that your initial reaction to your encounter was to think "demon" and that I experienced this similar encounter after actively seeking a demon. I don't know if I would call it a demon or not -- I don't have any evidence to swing either way -- but I would like to submit the possibility that a superpowerful otherwordly entity may stop at hiding behind a radiator and breathing simply because it needed some form of allowance in order to do more. Which would explain why in my experience I actually had physical interaction with whatever it was, simply because I had expressly asked for it. Who knows? I just thought that now would be the right time to share this experience with you seeing that there are some uncanny similarities and all.
