Why does fasting increase lucid dreaming?

Fasting may increase lucid dreaming due to the changes it induces in brain chemistry and sleep patterns. When the body is in a fasted state, levels of certain neurotransmitters, like dopamine, may rise, enhancing dream vividness and cognitive clarity. Additionally, fasting can lead to longer periods of REM sleep, where most vivid dreaming occurs, increasing the chances of becoming aware that one is dreaming. This heightened awareness can facilitate the experience of lucidity during dreams.
