I'm going to start by mentioning I am a skeptic. Not to say that I don't believe paranormal occurrences can take place I just try to find the most rational explanation first. The house I live in is making it hard to deny the fact that there is something wrong here.
The earliest occurrence I can remember a friend and I were up late chatting and the subject of ghosts was brought up. We're both adults, I believe we were 24 and 22 at the time, and were just passing the time with good conversation. After a couple hours we start looking up "real" ghost videos online. We muted the computer as it was quite late and didn't want to wake my now fiancé sleeping down he hall if we found one of those "jump" videos with the scary face flash and loud scream. Most of what we found was easily faked or obviously meant to be a spoof.
One video really caught our attention though. It was a compilation of several videos that reminded us of experiences we had. Some we had just discussed, in fact. The final clip was the longest and for most of the beginning of the clip nothing was happening. We both got in really close on the screen to try and figure out what the video was trying to show. It was a child's room, looked like it was from the 70s or 80s and the video quality matched. In the foreground was a picture of Jesus making the "I have big spikes through my hands" face, wearing the crown of thorns. The background was a closet with one of those toy clocks, the ones where if you spin one hand they both spin at the appropriate speed, hanging on the inside of the open door. After almost giving up and moving on to the next video the hands on the clock began to spin. Slowly at first, and gradually more rapid until it was bouncing against the closet door on which it was hung making a thumping sound.
I look over at my friend who is now about ten shades whiter than usual and slack jawed. I inquired about his reaction and he replied with, "The computer is muted." I don't remember where I was going to go with my reply but I got out a, "Yeah, but" before he pointed at the icon on screen and the lit mute button on the laptop and said, "No, Pink, the computer is muted." Suddenly it occurred to me that there should be no way we could hear the clock thumping away on screen. We both backed up fast onto the couch behind us. Two grown men cuddling on a couch arguing over who has to shut the laptop, which was still thumping, getting louder. We decided that both of us jumping up, slamming the laptop shut, and running out of the room was the best course of action.
Scariest part of this particular happening is a few months later we were having another one of our "let's tell stories that will freak us out nights" and my brother was in attendance. So we wanted to see if we could get the muted computer to make noise with that video again. Problem is we scoured the Internet to find it to no avail. Literally no trace of it on any video hosting site we could find.
This was as far as I'm concerned the night that started it all. It took longer than I expected to type this out on my phone so I'm going to break here and post the next memorable experience tomorrow.
