Hello Peyton,
In this dream where you find yourself attempting to play your Xbox and getting frustrated as it shuts off, it could symbolize feelings of interruption or disruption in your waking life. The elements from 'Finding Nemo' and the 'Five Nights at Freddy's' fan game may represent a longing for the comfort and control found in familiar entertainment when faced with uncertainties or interruptions. The fact that the console turns off when you are doing something else might suggest a sense of being overwhelmed or distracted by multiple responsibilities or concerns.
Reflecting on your previous dream about losing your purse at school, there seems to be a recurrent theme of anxiety related to losing control or important aspects of your life. This, combined with the interruption in your recent dream, suggests a potential feeling of instability or concern over keeping things together in situations where you're not fully in control.
Considering the life events you've experienced with the loss of family members, it's not uncommon for such significant events to surface in dreams as metaphors for the feelings of loss and the interruption of normality in your life. It's possible that your dreams are processing these emotional disruptions, manifesting as themes of loss and the unexpected turning off of your Xbox.
Your dreams seem to be reflecting a search for stability and a struggle with control, which could be tied to your life's transitions and the emotional impact of your losses. While the content of your dreams pulls from various interests, the emotions they evoke appear to be consistent with these underlying feelings.
