Staring at the wall

Princess Cherry has been missing for a long time. However when she's back she is a different person, not only did her personality change but as well as her actions. She tends to often stare in to space for a long time, as well as having a sharper vision in at night time.

So what happens durning her 'sleepwalks' durning the night, is she really sleepwalking or is there something more to it?
