What you perceive is a kind of virtual reality similar to a video game. It's just constructed based on sensory input, but still has a coordinate system and a point of view, like the camera location in a game engine. Electrically stimulating certain regions of the brain can change the point of view, leading what is called an out-of-body experience. You may wonder how it is that you can move the camera location without moving the eyes. That's because the sensory input creates a kind of 3d model and just like you can imagine what if would be like to see the room from another angle, you can also "hallucinate" it.
