keep hearing a phone vibrate as if someone got a silent notification in my bedroom. Mind you I'm on my phone and i swear a device is vibrating every 15 or so minutes. I've scoured my apartment with a flashlight looking for what it could be. It's not your standard phantom vibration because I'm not feeling pulsing or sound from my own phone. Don't have a neighbor on the side of the wall that my bedroom is in, definitely doesn't sound as if it's it could be upstairs neighbors. I'm talking like 4 feet away from me, clear as day. 
Body has fought off benadryl, my sleeping meds, and I'm extremely paranoid. Time to check in with the doc?
