I'm pretty sure it has to do with a chemical or something of the like that our brain produces when it senses we're tired and should go to sleep, making us feel hazy and start having dreams. The reason I'm leaning towards a chemical release in the brain is because I've felt such a thing a couple of times, maybe 5-10 times in my life.
Melatonin helps regulate sleep-wake or circadian rhythms. Normally, production of melatonin by the pineal gland is stimulated by darkness and inhibited by light. Melatonin can suppress libido by inhibiting secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH) from the anterior pituitary gland -- especially in mammals that have a breeding season when daylight hours are long, such as sheep. Nobel Prize laureate Julius Axelrod performed many of the seminal experiments elucidating the role of melatonin and the pineal gland in circadian rhythms. Beta blockers decrease nocturnal melatonin release.
Although many brain chemicals are involved in sleep and dreaming, two very important ones are the neurotransmitter serotonin and a brain hormone called melatonin. Both are produced by the pineal gland of the brain" (1). Melatonin is meant to calm the brain and induce sleep. Serotonin on the other hand triggers the brain to dream.
