our gliders can get spooked and act differently alot. sophie is our most bonded and she is sweet and sleeping during the day, sleeping and grooming. At evening her morning she is more active and wants to jump on your arm. I visited her at 2:30 am, she was completely awake and very jumpy (squirrely). seems like it takes her a minute to get my scent and settle down.
My thoughts are something got your glider scared, so it was being jumpy like waking from a nightmare.
