One thing Alexandra didn't know about the device was that the previous owner had left it in serious disrepair. So despite the configuration it had, the transformation could be somewhat random.
Throughout the night, Alexandra was transforming in many ways while she was still asleep. At one point she had regressed to a certain age and then regressed to another age. Sometimes her gender would change and other times she would go back to normal. It was by sheer luck that Alexandra hadn't woken up yet only to find out how her body changed every so often.
Finally, there was a point where the device finally stopped working and consequently ended up leaving Alexandra in a random transformation. Fortunately, her gender had returned to normal but her age was still altered.
When morning came, Alexandra would finally start to wake up only to discover that she was now _____ years old.
