Hallucinations, whether revelatory or banal, are not of supernatural origin, they are part of the normal range of human consciousness and experience.

The potential for hallucination is, it seems, in all of us.

Amplifying a theme that resounds throughout the pages of Hallucinations: 'We see with the eyes, but we also see with the brain. And seeing with the brain is often called imagination.'

One can have hallucinations and not be mad. And this is a very important thing to remember.

If we hope to meet more of our reality, then we have to meet more of ourselves.

The world is a projection, ultimately, of our nervous system, as much as the brain is.”

Hallucinations don't belong wholly to the insane. Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury.

What one sees is not only a matter of refracted light but is deeply influenced by one's own cultural and personal assumptions.

People can be haunted by their perceptions in ways beyond understanding.

We are creatures, and it is our nature to prefer beliefs to uncertainties.

We may think there is a clear distinction between 'reality' and 'imagination,' but this is not entirely correct.
