Know exactly how you feel girl. And having no control is frightening.
We had one in Lincolnshire, England last month that was also 5.2. I can normally sleep through anything so it finally got through to my sleepy head just as it was coming to an end so i woke to the bed shaking like crazy and doors banging (its a very, very large heavy Kingsize solid wood bed!) and I quickly asked B what was happening close to tears. He turned round, touched me gently on the arm and said "It's alright babe, it's just an earthquake". Ha ha - like it's the most natural thing in the world here (not). Funny thing is I was so relieved to find out it was an earthquake rather than something supernatural lol. I kept saying "you're sure it's not supernatural?" and he said "yes dear". So I just went back to sleep. He'd been wide awake before it happened so he's been able to rationalise straight away and so remain calm.
There was a lot of damage to homes 11 miles away at the epicentre though so we were lucky :-)
There was another earthquake last night in the same place last night in Evansville IN. I didn't feel it though. There aren't any specifics about it yet.
There were two small ones before the big one in New Madrid.
