Hallucinogens: psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input. LSD: a powerful hallucinogenic drug; aka acid (lysergic acid diethylamide). Near-Death Experience: an altered state of consciousness reported after a close brush with death (such as cardiac arrest); often similar to drug-induced hallucinations. THC: the major active ingredient in marijuana; triggers a variety of effects' including mild hallucinations.
Stimulants: drugs (such as caffeine, nicotine, and the more powerful amphetamines, cocaine, Ecstasy, and methamphetamine) that excite neural activity and speed up body functions. Amphetamines: drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes. Nicotine: a stimulating and highly addictive psychoactive drug in tobacco. Cocaine: a powerful and addictive stimulate, derived from the coca plant, producing temporarily increased alertness and euphoria. Methamphetamine: a powerful addictive drug that stimulates the central nervous system, with speeded-up body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels. Ecstasy (MDMA): a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition.
Depressants: drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body function. Alcohol Use Disorder: (popular know as alcoholism). Alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use. Barbiturates: drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgement. Opiates: opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety.
Suprachiasmatic Nucleus (SCN): a pair of cell clusters in the hypothalamus that controls circadian rhythm. In response to light, the SCN causes the pineal gland to adjust melatonin production, thus modifying our feeling of sleepiness.
REM Sleep: rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. AKA paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active. Alpha Waves: the relatively slow brain waves of a relaxed, awake state. Sleep: periodic, natural loss of consciousness-as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation. Hallucinations: false sensory experiences, such as seeing something in the absence of an external visual stimulus. Delta Waves: the large, slow brain waves associated with deep sleep. NREM Sleep: non-rapid eye movement sleep; encompasses all sleep stages excerpt for REM sleep.
Circadian Rhythm: the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.

information-processing perspective proposes that dreams may help sift, sort, and fix the day’s experiences in our memory.
sigmund freud on why we dream: proposed that dreams provide a psychic safety valve that discharges otherwise unacceptable feelings
manifest content according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content). latent content according to Freud, the underlying meaning of a dream (as distinct from its manifest content). REM rebound the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM sleep).
our mind also monitors our environment therefore we can dream of a certain smell because we can smell it in real life in our environment.
story line of our dreams incorporates traces of previous days’ nonsexual experiences and preoccupations
dream a sequence of images, emotions, and thoughts passing through a sleeping person’s mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer’s delusional acceptance of the content and later difficulties remembering it. manifest content according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content). latent content according to Freud, the underlying meaning of a dream (as distinct from its manifest content).
insomnia- recurring problems in falling or staying asleep. narcolepsy- a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times. sleep apnea a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings. night terrors a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during NREM-3 sleep, within two or three hours of falling asleep, and are seldom remembered. Sleep walking and sleep talking run in families
Subtopic
sleep strengthens memory, increases concentration, boosts mood, moderates hunger and obesity, fortifies the disease-fighting immune system, and lessens the risk of fatal accidents
“Sleep deprivation has consequences—difficulty studying, diminished productivity, tendency to make mistakes, irritability, fatigue"
predictor of depression
without sleep you are not able to concentrate at the task at hand and you will feel much less motivated and be less precise in your work. Your level of satisfaction (as in your mood) can also corelate to how well you are sleeping.
after not having enough sleep for countless nights, your brain begins to carry a "debt" of amt of sleep lost. You can not repay this debt back with one night of long long sleep
Our attentional spotlight and interpretations powerfully influence our ordinary perceptions. -hypnosis involves not only social influence but also a special dual-processing state of dissociation -selective attention can play role as well in hypnotic pain relief
- To some extent, we are all open to suggestion -being under hypnosis does not make you act out against your will -can be therapeutic -
some things that DO take conscious effort, with effort it can become like second nature- William James called this a continuous “stream of consciousness,”
