theweirdtophat,
This happened to me after I was messing around with EVP for a couple of months a year ago , very long story, but yes, I began to hear voices outside of just my recordings. I heard them in various ways, alot of times it was right up to my ear it seemed and I even felt a faint breath, sometimes it was whispers, sometimes it seemed to come in over an existing sound. It was terrible for months, the voices were constant and very overwhelming. I also experience alot of physical sensations, vibration feelings and such. I was perfectly fine before I started dabbling with EVP, and in just a couple of months I got hit with this. It is very real. I have been collecting accounts as well over the last year. I'm still dealing with it today, but it's not nearly as intense as it was a year ago. I do believe it is spirit attachment. Whenever I talk about this on an online forum I am usually hit up with mental illness comments but if you want to send me a PM, I'll forward you what info I have and somemore of my story, I would also be interested to hear what you know about this phenomenon.
