The pineal gland is a receiver for transmissions from higher dimensions and the prefrontal cortex is the processor.
It is a shame that "scientists" broke the world into physics and metaphysics.
The culture of scientism is toxic, but metaphysics is something you've already been doing since birth. Nobody can take that away from you.
