People all over the world have encountered voices from the other side, by electronic appliances or other. I always tried to contact a ghost, but failed miserably. I was twelve at the time. I was always been haunted when I was a kid. It's like the spirits always contact me, but I never respond back.
First, I used a tape recorder. I could only hear static. It's that kind of recorder that has a light and when someone is talking it flashes. It's available everywhere! I tried it for a week straight and no luck. I tried to call out for the sprits, but that didn't work either.
Next, I used a video camera. I set it up in the corner of my room to see if any spirits appeared. I tried that for a week straight. Nothing happened, but there were some weird shadows. The shadows are explainable! I had a lot of junk in my room and sometimes it could form a strange shadow.
Finally, this experience was the true way to contact the dead. I was minding my own business, until I dozed off just a little. I heard a voice on a radio. I thought it was just a dj, but I noticed that the frequency didn't exist on my radio. I didn't know how the dial turned to that station; maybe I turned it by mistake while napping. The voice seemed to be crying for help. There was nothing I could do, but it had a story to tell and maybe it wanted someone to listen his / her stories. I listened.
Apparently, there was a suicide that went on in my grandmother's house about 50 years ago. Whoever it was hanged them self. I didn't know if it was a women or a man, but the voice was mumbling in cries.
I had other experiences than this from technology. I'm trying to prove the world that the dead are beyond the grave.
