What just happened?

My chinchilla as chewing on an Apple stick when she suddenly stopped, went to the top of her cage, and it looked like one side went limp. I noticed one ear was pink and warm(on the side that looked limp) but the other was up and normal temp feeling. The temp in my room is a constant 63. I looked at her eyes and she just was staring at the wall and letting me handle her. She stayed like that for a minute maybe less then started hoping around again. She's acting like her normal sassy self.

What happened, was this a mild a seizure?
