sitting weird

Talia has been very vocal for days now. She walks around making hm noises(like apuppy cry high pitched hmhmhm). It was making me keep a close eye on her. She has begun running into her hut and rolling over. I'm not sure if she's just being weird (she used to do that behind her ramp years ago). Last night I became very worried. She went into her cage and stood on her hind legs and her tail began wagging. Later that night I found her standing on her hind legs on a cage shelf, but her butt was lifted off the floor, like a squat, but on her hind legs. She did not pee or anything, she was just in a daze for a minute and snapped out of it. She is still eating and drinking. She still runs on her wheel and ran around at play time.
Does this sound like anything to be concerned with or am I just being paranoid?
