=== Melatonin ===
{{Main|Melatonin}}

Melatonin is a natural hormone secreted by the brain's [[pineal gland]], inducing nocturnal behaviors in animals and sleep in humans during nighttime.  Chemically isolated in 1958,  melatonin has been marketed as a [[sleep aid]] since the 1990s and is currently sold in the United States as an over-the-counter product requiring no prescription.  Anecdotal reports and formal research studies over the past few decades have established a link between melatonin supplementation and more vivid dreams.<ref>{{cite journal |title=Effects of melatonin on dream bizarreness among male and female college students.|last=Kahan |first=Tracey L.  |year=2000 |journal=Sleep and Hypnosis |volume=2 |issue=2 |pages=74–83|url=https://scholarcommons.scu.edu/psych/102/}}</ref>
