Episode notes

During sleep and dreaming, our brains have lower levels of noradrenaline, leading to divergent thinking characterized by broad, imaginative, and creative associations. This state allows for more noise and less signal, fostering a creative process that involves making looser associations and exploring wider connections rather than seeking the shortest route. In contrast to convergent thinking focused on tasks, divergent thinking plays a crucial role in creative ideation and imaginative processes.

Have you ever woken up from a vivid dream and wondered about its meaning? Or perhaps questioned the purpose of dreaming altogether? It’s certainly a fascinating topic and one which I have never covered before on my podcast.

This week, I’m delighted to welcome back Dr Rahul Jandial, a dual-trained neurosurgeon and neurobiologist. He is an expert in brain health, a world-renowned brain surgeon who routinely undertakes complex cancer operations and he’s also the author of the brand-new book, ‘This is Why You Dream: What Your Sleeping Brain Reveals About Your Waking Life’.

During our conversation, Rahul explains his belief, that we sleep, in order to dream. When we are asleep, our brains are not resting but instead shift into a different state where areas linked to imagination and creativity become more active.

While dreams remain a largely unexplained phenomenon, Rahul shares his insights into common dream themes, the importance of dreams in childhood brain development, and the highly personal nature of dream interpretation. He also covers practical techniques for remembering dreams, the concept of lucid dreaming, the potential links between dreaming and future brain health, and also shares some profound insights about the brain at the time of death.

Throughout our conversation, Rahul emphasises that although dreams have captivated humans for centuries, they remain a mysterious and intensely personal aspect of our lives. However, if we approach our dreams with curiosity, they have the potential to gift us valuable insights about the contents of our minds and our emotions.

The topic of dreams clearly resonates with many of you - I received over 1,000 comments and questions about dreams when I announced this upcoming episode on my Instagram page. And, I’m happy to say that Rahul answers some of these questions throughout our discussion, offering his unique perspective as both a neuroscientist and a neurosurgeon.

So whether you're a vivid dreamer or someone who rarely remembers their dreams, this episode offers a captivating glimpse into our sleeping minds.
