“Cheese gives you nightmares”

The idea that a late-night cheese snack can lead to unsettling dreams is a long-standing misconception, woven into popular culture for centuries. This old wives' tale gained significant traction through works like Charles Dickens' *A Christmas Carol*, where Ebenezer Scrooge famously blamed his ghostly visions on "a crumb of cheese." Later, early 20th-century comic strips such as *Dream of the Rarebit Fiend* further cemented the humorous notion that indulging in cheesy dishes before bed could result in bizarre and disturbing nocturnal experiences.

However, scientific inquiry has largely debunked the nightmare aspect of this myth. A notable 2005 study by the British Cheese Board, involving 200 volunteers, specifically investigated the effects of eating various cheeses before sleep. The findings revealed that not a single participant reported nightmares. Instead, the study suggested that different types of cheese might influence the *content* of dreams, leading to distinct themes. For instance, Stilton cheese was associated with particularly bizarre dreams, while cheddar reportedly produced dreams involving celebrities.

The plausible connection between cheese and dreams likely stems from its chemical composition. Cheese contains tryptophan, an amino acid that can promote relaxation and aid in sleep by facilitating the production of serotonin and melatonin. Conversely, some aged cheeses also contain tyramine, a compound that can trigger the release of noradrenaline, a neurotransmitter linked to brain activity during dream sleep and potentially vivid dreams. Beyond specific compounds, the general act of eating a heavy or fatty meal, like cheese, close to bedtime can lead to indigestion and discomfort, which may interrupt sleep and make dreams more memorable or disturbing. Furthermore, recent research suggests that for individuals with lactose intolerance, consuming dairy products before bed can cause gastrointestinal distress, which in turn may contribute to more frequent and intense nightmares. This discomfort and disrupted sleep can make people more prone to recalling their dreams, including any unsettling ones, reinforcing the long-held belief.
