I have found that eating one or two bananas before going to bed causes me to either dream more or remember my dreams better. Even better(for myself, as I usually wake up around 3-4 a.m. every morning, then go back to sleep after a while) eat a banana if you wake up in the night, then go back to sleep.
(I read on a message board somewhere, where another person said this worked for them.)
Bananas are high in L-Tryptophan. L-Tryptophan is converted to 5-HTP, which is converted into serotonin.
Curious however, is that the serotonergic system shuts down during REM sleep(
http://www.antidepressantsfacts.com/pinealstory.htm).
"Dreams are hard to remember because noradrenaline and serotonin are virtually unavailable during REM sleep. These substances are needed to record memories. You can recall a dream that immediately preceded awakening, because the noradrenaline and serotonin systems come back online as you wake up. But if you shift your attention at all while you wake, you will often find that the memory of the dream vanishes."

Effects: Drowsiness, euphoria, and mental changes similar to mild (5 mg) dose of psilocybin.
Contraindications: Tendency to fall asleep. Excessive use could

http://www.bananaland.com.au/topmenu/facts.phpIF there is a definite increase in dreaming or dream recall, I am curious what is the mode of action?
Edit addition:
Melatonin is a neurotransmitter/hormone that is only active during sleep. It is being
metabolized when you fall asleep from Serotonin, a neurotransmitter that is being metabolized
from the amino acid Tryptophan. Melatonin increases non-REM sleep and makes it easier for you
to fall asleep. But it has also an interesting rebound effect that gives more frequent and
vivid dreams. The vividness might even give you a lucid dream.
From
http://www.faqs.org/faqs/dreams-faq/general/One person said of 500mg L-Tryptophan and 3 mg melatonin: "Not only did the combination of these two produce a pronounced drowsiness and eventually a deep sleep, but after several nights I began to notice that I was remember more dreams than normal." From
http://www.erowid.org/experiences/exp.php?ID=5336 Melatonin is metabolized to very interesting compunds, including 5-methoxy-tryptamine. This chemical may be involved in inducing REM sleep with vivid dreams. 5-methoxy-tryptamine and other tryptamines. Our brain manufactures its own hallucinogens which lead us to dream.
