July 4, 2025 – Weird dreams and vivid nightmares following late-night consumption of cheese products are surprisingly common complaints. Studies investigating the relationships between food, sleep, and dreams confirms a number of foods you eat before bed may indeed have a very real impact on the night ahead.
Dream neuroscientist Tore Nielsen of the University of Montreal, who led the study, is often asked whether food affects dreaming, and has published research on the topic before.
In the new study, he and his team recruited 1,082 psychology students from Canadian MacEwan University to undertake an online survey that probed their food habits, sleep time and quality, dreams, and nightmares. It also assessed their perception of how certain kinds of food, and time of eating, impacted their sleep and dreams, if at all.
