I have also heard that cheese is supposed to work well. I pulled it off of another website, but to avoid spamming links, I'll just provide you the excerpt of the explanation.

Cheese contains certain amino acids
tryptophan - shown to reduce stress and induce sleep
phenylalanin - under the right conditions, stimulates the waking part of the cortex.
I personally have found that it does help you have more vivid dreams, I'm not sure about bizarre though.
