really fucking creepy

im on my boyfriends desktop computer in our guest bedroom its completely dark and i’m alone. i thought i heard something on the speakers so i reach my hand up to the control to turn it up and it gets louder just when i move my hand next to the receiver. i turn the volume up and the noise goes away. i turn the volume completely off but leave my hand there and you can clearly hear people louder now speaking in a foreign, language. they were yelling or at least arguing about something. it only lasted a few minutes and i can’t get it to come back again. a barely audible talking kept fading in and out every few minutes but stopped. that’s crazy. wtf kind of interference can come through wifi speakers like that?
