Have you ever had a weird dream after indulging in a late-night cheese snack? You’re not alone—and now science is catching up with what many people have long suspected.

A new study from Canadian researchers has found that certain foods, especially dairy and sweets, may contribute to vivid or unsettling dreams, particularly when consumed close to bedtime. For some individuals, especially those with lactose intolerance or food allergies, these nighttime snacks may even contribute to nightmare disorder and disrupted sleep.

What Did the Study Find?

Led by neuroscientist Dr. Tore Nielsen of the University of Montreal, the research surveyed over 1,000 university students about their eating habits, dream patterns, and overall sleep quality. Key findings include:

• Dairy and sweets were most commonly blamed for unusual or disturbing dreams.
• 22% of respondents blamed dairy, and 31% blamed desserts or sweets for strange or distressing dreams.
• People with lactose intolerance or food allergies experienced significantly more nightmares and poorer sleep, likely due to gastrointestinal discomfort that interrupted restful sleep.
• Individuals who followed a healthier, more intuitive diet reported fewer nightmares and better dream recall.
• Poor sleep caused by GI symptoms may contribute to a negative dream tone and fragmented sleep cycles.
