Final answer:
Brigette's day-dreaming signifies an altered state of consciousness marked by reduced awareness of surroundings and a disruption in the continuity of thoughts.
Step-by-step explanation:
When Brigette is day-dreaming, she is experiencing an altered state of consciousness. This altered state is characterized by a couple of psychological characteristics. Firstly, there is a reduction in awareness of her surroundings, as her focus is turned inward towards her thoughts or imaginary scenarios rather than what is happening around her. Secondly, there may be a disruption in the continuity of her thoughts; her mind may drift from one fantasy or thought to another without a clear logical progression that is typical during full wakefulness.
