Is it possible to get nightmares from eating cheese? From eating certain kinds of cheese right before bedtime?
To find the answer to this, the British Cheese Board did a 'scientific investigation' in 2005 to find out. Participants were asked to eat a small three ounce piece of cheese before going to bed. That night, they kept a record of their dreams and nightmares to see if they got any patterns and or could induce cheese dreams.

75% of them were able to slept pretty well each night and most of the 75% were able to remember and report their dreams. The conclusion was that the essential amino acid in cheese, L-Tryptophan, was having an effect on the cheese-eaters by making their sleep patterns normal, and reducing any stress levels. People eating Blue Stilton cheese before bedtime reported very vivid dreams - not necessarily nightmares, but certainly weird in their content.
The common Cheddar cheese generated more dreams about celebrities, while Cheshire cheese created a nice, dreamless sleep. Red Leicester gave dreamers nostalgic dreams, childhood content, and Lancashire produced dreams of work - definitely a nightmare for some dreamers!
So, does eating cheese give you nightmares? It looks like the answer is no, though it appears to increase dream intensity, which helps you remember more dreams, produces more vivid and emotionally charged dreams, and makes it easier to have lucid dreams. In my case it gives me longer dreams, the same thing I get from L-Tryptophan supplements..
