I woke up this morning with my phone in my bed next to me instead of across the room on the charger. I checked the incoming calls and apparently Restricted called me twice at 8:06am for 15secs and 8:12am for 31 secs. I have absolutely no memory of this whatsoever. I'm assuming wrong number based on the short length of the call and the fact that if it had been relevant to anything, the importance of it would've woken me up.
Still, it's a bit disturbing because, as I said, I have no memory of it.
