That's a fascinating link, but my materialistic understanding is that the brain is an analogue signal processor, and tries to pattern match incoming signals to known experiences. In this case the input activates the "there is someone with me" signal. Doesn't mean there is. The brain is not a digital CPU, where every behaviour is a result of specific purpose-made circuitry. There is no "God detector" system in the brain.
