Inside Riley's Mind

This is Riley a 11 year old girl in 6th grade who loves her family and ice hockey. She was uprooted from her happy and simple life in Minnesota and taken to San Francisco, California where she experiences various changes in her life.

Do you ever look at someone and wonder what is going on inside their head? Well this is Riley mind and I am going to show you all about it.

Riley's Mind Is a metaphysical place which encompasses all the aspects of her consciousness.

Locations: 

• Headquarters: the central part of Riley's mind, where Anger, Sadness, Fear, Disgust and me Joy live and control Riley, and where her memories are produced.
• Islands of Personalities: five prominent constructions standing just on the edge of the Memory Dump. They represent defining aspects of Riley's personality, as determined by the core memories
• 
  Long Term Memory: enormous banks of memories forming one of the most omnipresent parts of
  the mind.
• Imagination Land : a place where everything Riley imagines is built.
• Dream Productions: where dreams are filmed.
• Subconscious: contains Riley's worst fears.
• Abstract Thoughts: a place where ideas (or anyone inside) are simplified to an abstract concept.               
• Train of Thought: a train that connects Headquarters and the rest of the mind.
• Memory Dump: an abyss surrounding Headquarters, where faded memories end up and eventually disappear.

When Riley is awake, the "sky" is lit up. When she is asleep, it goes dark, revealing the glow of the memories stored in Long Term. When Riley's personality breaks down as she runs away, the sky becomes gray like a gathering storm.

Additional Information:

It would appear that Headquarters acts as the main source of illumination (the sun and moon) inside Riley's mind, as everything lit in Riley's mind tends to face headquarters. There is also a strong "sun like" glow emitting from HQ when looking directly at it. 
According to Sadness, the expanses of Riley's mind are endless and do not have a set ending point. Far off in the distance of her mind, as seen in a few shots, are larger structures sticking up like buildings. Upon further examination, many of them seem to still be shelves of Long Term Memory, only taller in height.
