Nearly all adults experience dreams, with a recent survey finding 93% of French adults dream at least occasionally, and 30% reporting nightly occurrences. Beyond the often-bizarre narratives, research increasingly points to dreaming as a vital neurological process, possibly serving as “intense training for the mind” while we sleep.This article explores the science behind dreams – from the brain activity thay trigger to the common themes they present – and unpacks what our nocturnal adventures might reveal about our waking lives.
Nearly all French adults – 93%, according to a recent Ifop survey – experience dreams at least occasionally, with 30% reporting that they dream almost every night. Understanding our dreams can offer valuable insight into our emotional and mental wellbeing, and researchers are increasingly focused on the powerful role sleep plays in cognitive function.
While dreams can be pleasant, they often take a turn into the unsettling. Common dream scenarios include feeling perpetually behind schedule or facing endless tasks. A significant portion of those surveyed – three-quarters – reported dreaming about work.
Dreams Feel Real Because They Activate the Same Brain Regions as Waking Life
Following dreams related to work, erotic dreams are among the most frequently reported. These experiences are more commonly reported by men, with 78% saying they’ve had an erotic dream, compared to 61% of women.
The vividness of dreams, even those that seem far-fetched, is a key factor in their impact. Dr. Rahul Jandial, a neurosurgeon and researcher, explains, “Dreams affect us profoundly because we live them as real.” He adds, “The joy we feel in our dreams isn’t physiologically different from the joy we experience when awake, nor is the terror, frustration, sexual excitement, anger, or fear.”

The joy we experience in our dreams is identical, on a physiological level, to the joy we experience when awake, just as is fear, anger, frustration, or sexual excitement.
Dreaming is Intense Training for the Mind
Dr. Jandial further explains the neurological processes at play during dreaming. “Run in your dreams and the motor cortex activates – the same area of the brain you’d use if you were running in reality. Feel the touch of a loved one in your dream and the sensory cortex is stimulated, exactly as it would be in reality.” He emphasizes the importance of dreams, noting, “Many of us have the ability to dream from the moment we fall asleep until we wake up, which means we could spend up to a third of our lives dreaming.”
The question of why we dream and what our dreams mean remains a topic of ongoing research. Dr. Jandial describes dreaming as “intense training for the mind.” During sleep, we experience vivid activities, imagined and felt with emotion, vision, and movement. This process keeps all parts of the brain active in a way that doesn’t happen during routine tasks.

The Meaning of Dreams… and Nightmares
The interpretation of dreams is highly personal, influenced by individual experiences, cultural background, and beliefs. Erotic dreams are particularly common, experienced by almost everyone at some point. There’s no need for embarrassment surrounding these experiences. Dreaming about someone other than your partner, or even about infidelity, doesn’t necessarily indicate unhappiness in your relationship; these dreams are simply a product of the imagination unleashed during sleep.
Nightmares, on the other hand, often reflect our emotional state, serving as a barometer of our overall wellbeing. One of the most universal nightmares is being chased, generally interpreted as a manifestation of stress, anxiety, or a situation we’re trying to avoid in waking life. Understanding the emotional roots of nightmares can be a helpful step in addressing underlying stressors.
