Date: circa Summer 2006
I cannot remember the exact date but all I know was that this encounter in particular was in 2006. One night I had turned the TV off and was trying to get some sleep. The moon was bright lit on this night and it was a clear sky, but I had the window blinds closed tight so the moon wasn't really shining in the room. I was just dozing off good when I heard a strong gust of wind blow against the window. I thought that it was getting windy outside and maybe a storm was coming, but it was strange because that was the only gust of wind. It didn't really even sound like "wind" per se, but more like a strong "pressure" against the window, if that even makes sense. I didn't think anything of it so I shook it off and tried to doze back off to sleep.
A few minutes later I heard the sound of very slight shuffling of something on my dresser. There were a couple of cans of body spray and a small pile of papers up there. The noise sounded as if someone brushed against one of the spray cans. I opened my eyes to see if anyone came in the room and was over by the dresser but I saw no one. I was startled slightly but I attempted to doze off once more. There was this slight strange feeling in the room but I wasn't really even thinking about it enough to really be aware that anything was wrong.
A couple of minutes later I heard the doorknob click as if someone turned it slightly and let it spring back and snap. If the noise on the dresser wasn't enough to get my attention, that noise sure was. I laid in bed for a minute trying to think what the hell was going on and then finally got up and went out into the rest of the house to see if anyone else was awake, but I found that everyone was asleep. After that I laid back down and eventually went off to sleep without further interruption.
It wasn't until the next day upon waking up that everything really started to sink in. It was just a very unsettling feeling when I thought that it was maybe a spirit passing through my room. The mere thought of the way it entered, with such pressure against the window, really got me to thinking.
The "flex" sound that I described is very intriguing indeed. Even being 10 years ago, I still think about it and I get goosebumps each time.
As far as the popping sounds you mentioned, you are right on. I have had many experiences in my home where we (my parents and I, mostly my dad) would hear this loud "pop" somewhere in the room, mostly always near a window, and it always seemed to have this "presence" behind it as if someone made a grand entrance into the room. Like you said, it sounded as if a spirit "broke" through the dimension.
Under normal circumstances a house is going to pop as it settles. As a matter of fact, as I type this now I am hearing popping noises at my bedroom window, but it is the house settling. It does this every morning. Getting back to the point though, those popping sounds we heard were always different from the normal occurrences, and we knew it would be a spirit (s) because soon afterwards we would feel a cold spot and a presence around. It was very freaky. We had some strange shiat to happen in our house.
