When I was about 12 or 13, I was doing some "treasure hunting," also known as thrift store/garage sale shopping. I was looking for some old jazz records to add to my collection.
As I was rummaging through various bins and shelves, I found an awesome ham radio. It wasn't in the greatest condition and the dial knob was missing, but I had to have it. I thought it would be cool to display it among my record collection. So, I bought it and took it home.
Naturally, the first thing I did when I got home was plug it into the wall to see if it even worked. I was surprised to see that the radio worked fairly well. It picked up a few AM radio stations. Of course it could only pick up AM radio stations as FM was non-existent at the time in which it was made.
That same night, as I was going to sleep, the radio turned on by itself. It was still plugged into the wall, so I didn't get freaked out about it. Seeing as how it was so old there was bound to be something faulty responsible for its turning on. I got out of bed and walked over to the dresser and turned it off. I crawled back into bed and went to sleep.
At about 3 in the morning I was awakened by what sounded like a garbled conversation. As I came to, I saw that once again the ham radio had turned itself on. But this time, the sound seemed different. In between the spurts of silence and static I could hear breathing. I yanked the cord out of the wall and went back to bed. I would check it out in the morning to try and figure out if the power switch was faulty.
The next day, sometime in the early evening, I plugged the radio into the wall and began tinkering with it. Then, the most terrifying thing happened. The static faded completely. The silence came back on as did the sound of breathing. Suddenly, the creepy voice of a man came on and said, "Hello, little girl."
I froze in fear. The voice came back on and said asked if I was "ready." Hell no, I wasn't ready. Ready for what? I didn't want to know. I pulled the plug out of the wall and threw that possessed radio into one of the dumpsters in my apartment complex.
Thankfully, that was my first and only encounter with the paranormal, but even today it sends chills down my spine just thinking about it.
