The discussion explores the differences between dreams and hallucinations from a neurological perspective. Key points include the activation of 5-HT2a receptors in hallucinations, which does not occur during dreaming. It is suggested that while dreaming is a natural process experienced during sleep, hallucinations often arise from conscious decision-making or mental disorders. The conversation touches on the variability of dreaming, with some asserting that everyone dreams regularly, even if they don't remember it. The role of brain activity during these states is debated, with some participants noting that dreams often lack coherence due to inactive brain regions. The discussion also highlights the intensity of experiences in dreams versus hallucinations, with lucid dreaming being mentioned as a state where all senses are engaged. Additionally, the effects of substances like DMT and the nature of hypnosis are examined, with some arguing that hypnosis can blur the lines between reality and imagination. Overall, the conversation emphasizes the complexity of understanding both phenomena and their underlying neurological mechanisms.

Repression.. Yes.

What can you conclude about those who can be affected by hypnosis?

hypnosis seems to create a focus of attention on the result of imagination while giving them the apparent level of energy necessary to be perceived as reality. Many people who are good subjects for hypnosis may be living in a state of mind that is part dream part real most of the time and so its easier for them to accept suggestions of imagined events as real events... Stage hypnotists have ways of combing the audiance for just such people. One thing I heard a while back is that even people who are normally not suseptible to suggestion can be pushed over the edge by a bit of trickery, like telling them that they see everying becoming reddish, and then altering the lighting.

Hypnosis should not be thought of as a tool for tricking or deceiving people exclusively. It is used often in therapy and to lower stress levels.

When someone is being hypnotized, later, when he doesn't remember the stuff he was doing, was a part of him sleeping?(similar to multiple personality disorder)

My buddy and I were talking about hypnosis and he told me that 1 hour of hypnosis is equal to hours of good rest.
