YES. I come back out to the living room after my shower and I hear something weird, so I mute the tv (which took me forever!) and I hear this like constant vibrate noise. Like a phone but it was just a constant brrrrrrrrrrrrr whatever noise. I'm trying to follow it and think it's the vent but then there's a duffel bag by the front door and I dig into it and see two glowing red lights briefly and then it stops. So by now I'm like wtf man. My sister had used it to go on some trip with a little friend (she's 9) and I went through THE WHOLE BAG. All the pockets too and there was nothing that would vibrate or even glow....I don't even know. I'm scared >.>
