my bun was asleep when all of a sudden she got up and started walking around her pen, staggering around, it lasted about 15 seconds and she ended up standing with one foot in her water bowl so i picked her up and held her and that seemed to snap her out of it. when i put her down she slipped a little when hopping away but after that she seems completely fine and is eating like normal. is it possible that she have gotten scared from a dream or could she have been sleepwalking?
