Scene from inception explaining dream virtual world creation.
Interesting filmic metaphor for our continual altering of reality.

Presents a sort of dystopian view, as one of the lead characters
uses the technology to relive the past dangerously, seeking comfort
in the escapism if proffers. On the other hand, the "architect" of
the dream world is able to break boundaries and creatively
reneogiate her conception of the real world.
