Before I go to bed I always switch off my phone so I don't get woken up by idiots phoning me at stupid o clock

I woke up at 1030AM to find a missed call from my mum at 3:50AM, I was completly confused as to why on earth she would be phoning at this time of morning, especially as we live in the same house. I checked around the house and I was the only one there, I started to panic!

I phoned my grandparents who are always home, but even they were not answering the phone...
