Ana Fernández-Arcos, neurologist: ‘There are people who give so much importance to dreams that they can change their lives’

Published on April 1, 2026

Ana Fernández-Arcos, a prominent neurologist, has dedicated her career to unraveling the complexities of sleep and the phenomena surrounding dreams. In a recent interview, she emphasized the profound impact that dreams can have on individuals, stating, “There are people who give so much importance to dreams that they can change their lives.” According to Fernández-Arcos, the significance placed on dreams can lead to transformative experiences that influence personal growth and mental well-being.

Recent advancements in sleep science have provided deeper insights into how dreams function and how individuals can harness them for their benefit. One of the most intriguing aspects of this research is the concept of lucid dreaming—the awareness that one is dreaming, often accompanied to control the dream’s narrative. Fernández-Arcos reveals that many people can train themselves to achieve lucidity in their dreams through various techniques, such as reality checks and dream journaling.

“This ability to control dreams opens the door to a wide range of therapeutic applications,” she explains. Therapists are increasingly using lucid dreaming as a tool to help individuals confront fears, process trauma, and alleviate symptoms of anxiety and depression. Fernández-Arcos notes that these practices can empower patients to take an active role in their mental health, fostering resilience and personal agency.

When discussing the significance of dreams in everyday life, Fernández-Arcos acknowledges the spectrum of beliefs surrounding their meanings. While some see dreams as mere byproducts of sleep, others attribute profound spiritual or psychological significance to them. “Dreams can serve as a mirror reflecting our subconscious thoughts and emotions,” she observes, suggesting that introspection through dreams can lead to greater self-awareness.

The neurologist also addressed common misconceptions about sleep and dreaming, such as the belief that everyone dreams equally vividly. “In reality, dream recall varies significantly from person to person,” she points out. “Some may have rich, colorful dreams, while others may remember little to nothing at all.” This variability can affect how individuals interact with their dreams, further complicating the narratives they construct around them.

As sleep science continues to evolve, Fernández-Arcos encourages a broader dialogue about the value of dreams in our waking lives. She advocates for integrating discussions about dreams into mental health conversations, as understanding and processing these nocturnal experiences can provide valuable insights.

In conclusion, the landscape of sleep science is expanding, with researchers like Ana Fernández-Arcos at the forefront. Her work not only sheds light on the fascinating world of dreams but also emphasizes their potential to foster change and healing in individuals’ lives. As more people learn to engage with their dreams, the transformative power of sleep may become an invaluable tool for personal development and therapeutic support.
