I was going to suggest the same as Little Dragon .... she is going to have a heightened senses for a while .... because she can 'hear' now everything is going to be processed with not only that basically 'new' sense but all the other ones will be heightened as well as she rewires her brain to have them work together again .... not that excuses acting out the way she is ~ she still needs to learn to 'cope with dignity' but it should hopefully be a short lived adjustment.
