A persistent problem with falling asleep or staying asleep.

Sleepwalking.

Temporary stopping of breathing during sleep, leading to momentary awakenings.

Uncontrollable sleep attacks.

Sudden loss of muscle tone.

Stages of sleep, including REM (rapid eye movement), progressing in this order zero to four, occurring in cycles throughout the night.

Every dream is potentially meaningful and influenced by neurological factors associated with sleep.

Slow brain waves associated with a relaxed, awake state.

Large, slow brain waves that occur during deep sleep.

A sleep stage marked by rapid eye movements, dreaming, and increased brain activity, resembling wakefulness.

The recurring pattern of sleep stages occurring roughly every 90 minutes.

Brain waves of high amplitude and slow regular rhythm, found during light sleep (stages 1-2).

Explanations for why we need sleep, including ideas about recovery and circadian rhythms.

The state of not getting enough sleep.

Theories suggesting that sleep is important for repairing and restoring the body.

Theories emphasizing the role of internal clocks in regulating sleep.

Our immediate awareness of our internal and external states, encompassing both our thoughts and feelings, as well as our surroundings.

The idea that our minds operate on two levels: conscious and unconscious. The conscious mind is aware of its processing, while the unconscious mind works without our awareness.

A roughly 24-hour cycle in our bodies that influences our sleep-wake cycle. It's regulated by internal biological clocks.

A biological rhythm that repeats more than once a day. These rhythms can influence various processes, including sleep stages.

A naturally recurring state of reduced consciousness characterized by altered brain activity, reduced muscle activity, and a decreased awareness of surroundings.

Although the exact reasons are still debated, sleep is essential for physical and mental health. It supports bodily repair, strengthens memory, and helps regulate emotions.

Sleep occurs in cycles, each containing distinct stages characterized by varying brain wave activity and bodily changes. These stages include light sleep, deeper sleep, and the REM stage.

The natural cycle of sleep and wakefulness that occurs in our bodies as part of our circadian rhythm.

Drugs that slow down the activity of the central nervous system (CNS).

Drugs that speed up the activity of the central nervous system (CNS).

Drugs that alter perception and create hallucinations.

The amount of alcohol in your blood, measured as a percentage.

A state of deep unconsciousness.

Our awareness of ourselves and our surroundings; our ability to think, feel, and perceive.

Sleep progresses through distinct stages: 1) Light sleep, 2) Deeper sleep, 3) Deeper still, 4) REM sleep, where dreaming occurs. This cycle repeats throughout the night.

Substances that alter the body's physiology, excluding food and nutrients.

Decreased effectiveness of a drug after repeated use due to the body becoming accustomed to its presence.

Two types: Physical tolerance (withdrawal symptoms) and Psychological tolerance (cravings without withdrawal).

The remembered story line of the dream.

The underlying meaning of a dream, often representing unconscious desires or wishes.

Freud believed that dreams represent the fulfillment of wishes often stemming from the unconscious mind, sometimes with sexual or violent themes.
