““In one marijuana experience, my informant became aware of the presence and, in a strange way, the in-appropriateness of this silent "watcher," who responds with interest and occasional critical comment to the kaleidoscopic dream imagery of the marijuana experience but is not part of it. "Who are you?" my informant silently asked it. "Who wants to know?" it replied, making the experience very like a Sufi or Zen parable. But my informant's question is a deep one. I would suggest the observer is a small part of the critical faculties of the left hemisphere, functioning much more in psychedelic than in dream experiences, but present to a degree in both. However, the ancient query, "Who is it who asks the question?" is still unanswered; perhaps it is another component of the left cerebral hemisphere. An asymmetry in the temporal lobes””
