In this episode of On Purpose with Jay Shetty, neuroscientist Dr. Rahul Jandial delves into the neuroscience and biology behind dreaming. He explains how brain activity during sleep drives different types of dreams and their connection to our underlying emotions, anxieties, and personal growth.
Jandial also explores the potential psychological and emotional functions of dreams, from rehearsing survival situations to processing difficult experiences. The discussion offers practical applications of dream work, including techniques to induce lucid dreaming, journaling for enhanced recall, and using dream imagery to address issues like recurring nightmares.

According to Rahul Jandial, the brain is highly active during sleep, contrary to the myth that it rests. Specific brain regions and neurotransmitters drive dream experiences: the executive network is dampened while imagination and emotion networks are heightened, allowing for less structured narratives.
Recurrent dream themes like falling or being chased mirror underlying electrical brain activity. Jandial notes that recurring dreams are not random but signify biological experiences like nightmares or erotic dreams.
Experts suggest dreams rehearse survival situations and process emotional dilemmas. Dream content often reflects daily anxieties. Jandial proposes dreams may metabolize difficult experiences, facilitating emotional regulation.
Highly charged dreams provide insight into the subconscious, revealing conflicts or growth areas. Recurring themes may indicate unresolved issues. Dreams contribute to human development: children's nightmares foster self-awareness, while end-of-life dreams offer reconciliation.
Techniques like the "mild" method of waking before REM sleep can induce lucid dreaming. Monitoring brain activity aids lucidity. Reflecting on symbolic meaning, especially of vivid dreams, provides personal insights.
Jandial and Shetty recommend journaling upon waking to enhance recall. Pre-sleep intentions can influence dream content. Incorporating dream work like imagery rehearsal therapy to re-script nightmares offers benefits.
1-Page Summary
Rahul Jandial explores the active state of the brain during dreaming, debunking the myth that the brain is at rest during sleep and examining how specific brain regions and neurotransmitter systems drive the unique features of dream experiences.
Despite the common belief that sleep is a time of rest for the brain, Jandial stresses that the brain is anything but inactive during this time. He states that our brain generates the same amount of electrical activity and burns as much glucose during sleep as when we are awake. He indicates the brain's need to dream by referencing that if we miss sleep one night, the subsequent night will have earlier and more intense dreaming periods, which he terms as dreaming "harder." Moreover, he notes that the brain's vibrancy during sleep can be measured by the electrical activity via electrodes, showing how sleep and wake states have distinct but overlapping patterns.
Jandial describes the transition from waking to dreaming as a shift in brain network activity, where the executive network involved in logic and reasoning is dampened, while imagination and emotional networks are heightened. This suppression of logic allows the brain to integrate daily experiences into imaginative and less structured narratives. The medial prefrontal cortex, which helps cultivate our life story, is notably active and may contribute to narrative aspects in dreams. Equally, the imagination network is free to construct various scenarios, encouraging divergent over convergent thinking compared to our wakeful state.

The neuroscience and biology of dreaming
The complex roles that dreams play in our psychological and emotional lives are explored through discussions with experts who suggest that dreams can serve as rehearsal spaces for waking life experiences and represent underlying emotions and conflicts.
Experts like Jandial discuss dreams as a form of "nocturnal therapy," proposing that dreams could be spaces where we rehearse for survival or process emotional dilemmas, potentially sparking creativity by enabling a looser connection of ideas with dampened logic to promote imagination.
Dreams may mirror our realities, encouraging preparation for internal matters, and can be seen as healing or learning experiences where emotional challenges are worked through. Jandial posits that emotionally charged dreams could be a subconscious rehearsal of life experiences and emotions, serving as powerful indicators of anxiety, fear, or unresolved issues, as evidenced by PTSD flashbacks or stress-related dreams symbolically representing current life predicaments.
Additionally, Jandial discusses how the dreaming brain helps process and "metabolize" the most difficult parts of one's day, touching on common dreams reflecting anxieties such as being late, concerns of public speaking, or symbolizing struggles through disease-related dreams. He raises the concept of the "nocturnal therapist," suggesting that dreams could be important for emotional regulation.
Jandial and Shetty hint at the function of dreams in memory consolidation and emotional processing. The discussion of dreams, as the brain's "shepherd" guiding emotional trauma, suggests that dreams facilitate internal problem-solving and adaptation to non-routine life challenges. Moreover, they indicate that the imagination network, liberated during dreaming, may have a role in emotional insight, evidenced by hyper-emotional dreams that carry into waking life.
Dreams, especially those that are intensely emotional, unusual, or recurring, can offer profound insights into one’s subconscious, revealing hidden conflicts or areas for personal growth.
Dreams filled with fright, regret, or that are exceptionally vivid and narrative-driven suggest a deeper engagement with daytime experiences and emotions, potentially indicating underlying psychological states. Erotic dreams about people one is not attracted to may point to power dynamics or deeper psychological processes.

The psychological and emotional functions of dreams
Engaging actively with one’s dream life is not just a passive experience, as Jandial and Shetty explain. There are methods to enhance dream recall, induce lucid dreaming, and gain valuable personal insights.
Jandial describes the "mild" lucid dreaming technique, which entails waking up a little earlier than usual and then striving to remain conscious while falling back to sleep. This method has been reinforced by a study where participants used eye movement patterns to signal lucidity and even solved simple math problems during lucid dreams. Jandial suggests, to improve dream recall, not immediately engaging with emails or social media can help. Additionally, he introduces a drug called [restricted term], which can induce lucid dreaming in a dose-dependent manner.
Talk about the placement of electrodes to measure electrical activity as evidence of sleeping during lucid dreaming experiments was discussed. Techniques like the aforementioned "mild" method and tracking tools can help facilitate an awareness during REM sleep, providing new ways to engage with the dreaming process.
Jandial advises that those dealing with emotionally powerful dreams should pay particular attention, as they might offer valuable insights or represent metaphorical or symbolic narratives unique to the individual's experiences and cultural context. Reflecting on these dreams can provide understanding and personal insights.
Imagery rehearsal therapy, as mentioned by Shetty, involves practicing a new script for the ending of nightmares, potentially altering the person’s emotional state upon waking. Jandial discusses the importance of noticing patterns rather than individual dreams unless they are extremely emotional, indicating the importance of seeing overarching themes that may reveal deeper insights from the subconscious.
