It is often said that eating cheese before bedtime will cause nightmares.
In 2006 the British Cheese Board - A nice play on words.
The British Cheese Board is the voice of British cheese
http://www.britishcheese.com/The BCB made efforts to wrong this belief by giving 200 volunteers different cheeses to eat before retiring to bed.
The report went on to state that that the volunteers experienced weird and colourful dreams but none had nightmares.
So cheese before bedtime will not give you nightmares
Staying on the the subject of dairy and sleep !
Milk contains an amino acid called tryptophan which in small quantities improves sleep.
Which in turn reinforces the the belief that a nice mug of warm milk before bedtime will aid a good nights kip.
