For me every time I happen to walk by a television set or a radio and I hear voices, the way they sound, it's just hard for me to tell myself these are actually not real or fake, made up in my mind.
These voices I hear sound like another transmission or something, so real and I also hear what sounds like a low frequency radio, or like when I have attempted to transform mono sounds to stereo sounds as well as the frequency in hertz sounds have a strange electronic sound, like high pitched, does not sound pleasing to the ear.
This happens when the television is playing or the radio. I may not even hear what it's really being said, just what sounds like this other transmission instead of what is going on on television for instance.
Maybe I should convince myself that this is REALLY in my head but in this day and age, I'm most likely just kidding myself, regardless what anyone tells me.
SERIOUSLY, let me give an example, are we all supposed to believe that mobile phones are compact magical boxes and nothing more than that? No, of course not.
