Title: Oneirology
Content:  Correlations between the usage of drugs and dreaming have been documented, particularly the use of drugs, such as sedatives, and the suppression of dreaming because of drugging effects on the cycles and stages of sleep while not allowing the user to reach REM. Drugs used for their stimulating properties (cocaine, methamphetamine, and ecstasy) have been shown to also decrease the restorative properties of REM sleep and its duration.

Content: Amanita muscaria (contains muscimol) ; Amphetamines and other stimulants can create psychotic episodes (called stimulant psychosis) which may be defined as bursts of dream activity erupting spontaneously into waking states; this is not due to the substance itself but rather a result of the prolonged suppression of cholinergic activity and REM sleep due to amphetamine or stimulant abuse. ; Artemisia douglasiana or California mugwort, Douglas's sagewort or dream plant, is a western North American species of aromatic herb in the sunflower family that can be used as a scent, tea, or smoke to trigger vivid and lucid dreams. ; Artemisia vulgaris ; Wild red asparagus root may 
Title: Dimenhydrinate
Content:  Dimenhydrinate is recreationally used as a deliriant. Slang terms for Dramamine used this way include "drama", "dime", "dime tabs", "D-Q", "substance D", "d-house", and "drams". Abusing Dramamine is sometimes referred to as Dramatizing or "going a dime a dozen", a reference to the amount of Dramamine tablets generally necessary for a trip. Many users report a side-effect profile consistent with tropane alkaloid (e.g. atropine) poisoning as both show antagonism of muscarinic acetylcholine receptors in both the central and autonomic nervous system, which inhibits various signal transduction pathways. Other CNS effects occur within the limbic system and hippocampus, causing confusion and temporary

Title: Cheese (recreational drug)
Content:  Some toxicologists questioned the results due to the absence of acetaminophen. Other experts argued that acetaminophen has a shorter half-life and might have been metabolized by the body prior to death. Susan Dalterio, a University of Texas at San Antonio pharmacology expert, insisted that the combination was unlikely to be a coincidence, as a person sleepy from diphenhydramine would be unlikely to be abusing heroin at the same time. It is common for users of heroin and other opioid drugs to take diphenhydramine-containing medications as an attempt to alleviate side effects resulting from histamine release induced by opioid administration, such

Title: Memory erasure
Content:  Drug-induced amnesia is the idea of selectively losing or inhibiting the creation of memories using drugs. Amnesia can be used as a treatment for patients who have experienced psychological trauma or for medical procedures where full anesthesia is not an option. Drug-induced amnesia is also a side-effect of other drugs like alcohol and rohypnol. There are other drugs that also can cause their users to be put in an amnesic state, where they experience some type of amnesia because of their use. Examples of these drugs include Triazolam, Midazolam and Diazepam.
Title: Death of Michael Jackson
Content:  Of all the drugs found in Jackson's home, the one that most concerned investigators were propofol (Diprivan), a powerful anesthetic administered intravenously in hospitals to induce and maintain anesthesia during surgery. Nicknamed "milk of amnesia" because of its opaque, milk-like appearance (and a play on the words "milk of magnesia"), the drug has been associated with cardiac arrest, but it still may be increasingly used off-label for anxiolytic and other medically unsubstantiated purposes. Several propofol bottles, some empty, some full, were found in Jackson's home. On June 30, Cherilyn Lee, a nurse who had worked as Jackson's nutritionist, said that he had asked her in May to provide propofol to help him sleep, but she refused. He told her
