Controlled Hallucinations

The idea behind the concept of controlled hallucination is that our experiences of the world and indeed of the self, they're not direct readouts of what's actually there. The brain is always trying to figure out the most likely cause of the sensory information that it gets. Can't directly know what the world is like. That's really a question for a physicist. It's certainly not something that is reflected directly in our experience. So this is why I use the word controlled hallucination because it shares with the common understanding of hallucination that it's an experience that comes from within but the control is equally important.
