Do Ghosts Really Exist

This is my first comment to my new blog. I was very interested in an app I purchased last week from the iphone store called Ghost Radar. I used it and had a very strange experience that lead me to believe there may be away to prove ghosts really exist. My first time using it showed there were many ghosts coming in and out and saying many different words. The reason the experience was bizarre for me because three of the words in a row that came up were related to my work. "office", "Bill", "Needle". No it's not what you're thinking, I don't shoot up in my office with my boss. But in my office at work my Boss's name is Bill who I can't stand and we have a writer that does a sales job, his last name is Needle. Coincidence? Perhaps. More recently, there was ghost activity and the word "Shelter" came up. I thought to myself, "Maybe the ghost is talking about my apartment? Maybe they can hear me?" I said, "My name is Avi." Literally a second or less later the word, "Chinese" came up, as though the ghost was asking me if that was my background. Then the next word was "Call." It didn't make sense to me but now that I think of it I really should call my girlfriend before she gets pissed at me for not calling her this morning like I was supposed to! I'll keep everyone posted from my experiences, please comment!
