Anywho I remembered the cheese thang was from years ago and I thought if people are interested they might want to have a go with it. I listen to NPR on my way to work so knew that's where I heard it and just now dug it back up ... the audio is very short BUT there is also the written transcript ... so here's the link ...
Study: Eating Cheese Can Alter Your Dreams
Mr. NIGEL WHITE is the Secretary of the British Cheese Board
Quote
Mr. WHITE: Well, we asked for a number of volunteers to eat a small piece of cheese about half an hour before they went to bed.
BLOCK: How small?
Mr. WHITE: Well, the amount of cheese was two-thirds of an ounce.
BLOCK: Not a lot of cheese.
Mr. WHITE: Not a lot of cheese. And the idea was that they would keep a diary of the type of sleep that they had, and also, if they did dream, could they remember what they dreamt about.
BLOCK: And what did you find?
Mr. WHITE: And they did this for a week, and we found that about three-quarters of everybody said that they slept well every night, and most of those people could remember the dreams that they had. So that was pretty encouraging. And the science of that, we think, is that there is an essential amino acid in milk called tryptophan. Now tryptophan is known to be something which is helpful in normalizing sleep and reducing stress levels. That seemed to make sense to us. What was really wacky was that the type of cheese that people were eating seemed to give them different types of dreams.

They go over what cheeses provide what types of dreams as well which I thought very interesting though scientifically a little squishy ... but still cool

That said there are many foods that effect sleep/dreams, the cheese thing is just cool, fun and specific so easy and tasty to try out.
Serotonin is produced from the amino acid tryptophan and that's just an easy explanation but probably only the tip of the iceberg. Spicy foods increase metabolism and body temperature which should drop when you sleep and may be what causes fitfulness or restless sleep. Caffeine in addition to making it more difficult along with other stimulants literally change how our


Anywho I don't mean to keep going on BUT there are lots of interesting angles to look at especially when you add in known issues like diabetes and blood sugar at night.
For those who want a tl:dr version of all this ... try eating cheese to tweak your dreams, and those just wanting good sleep try protein + carbs. Your

Incidentally cheese has a good amount of protein and energy
