Corolla won't start

I drove home to get something and when I come back out my car won't start, my power windows are down and will not function, no dash lights when key is turned to on position and it will not turn over, no radio, nothing seems to be working, only light I see is the door open indicator light and the security light is blinking but go's out when I insert my key into the ignition

I disconnected the negative battery terminal and left it off for an hour or so and it started right up when I reattached it but now has a rough idle, I have heard cars need to be driven about 50 miles or so to clear up the idle issue so I will try that when I have time to get it on the road.
