Dream

A dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep.
The content and purpose of dreams are not fully understood, although they have been a topic of scientific, philosophical and religious interest throughout
recorded history. Dream interpretation is the attempt at drawing meaning from dreams and searching for an underlying message. The scientific study of dreams is called oneirology.

Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake.
REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However,
these dreams tend to be much less vivid or memorable. The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes.
People are more likely to remember the dream if they are awakened during the REM phase. The average person has three to five dreams per night, and some may have up to seven;
however, most dreams are immediately or quickly forgotten. Dreams tend to last longer as the night progresses. During a full eight-hour night sleep,
most dreams occur in the typical two hours of REM. Dreams related to waking-life experiences are associated with REM theta activity, which suggests that emotional
memory processing takes place in REM sleep.
Opinions about the meaning of dreams have varied and shifted through time and culture. Many endorse the Freudian theory of dreams – that dreams reveal insight
into hidden desires and emotions.[qualify evidence] Other prominent theories include those suggesting that dreams assist in memory formation, problem solving,
or simply are a product of random brain activation.
Sigmund Freud, who developed the psychological discipline of psychoanalysis, wrote extensively about dream theories and their interpretations in the early 1900s.
He explained dreams as manifestations of one's deepest desires and anxieties, often relating to repressed childhood memories or obsessions. Furthermore,
he believed that virtually every dream topic, regardless of its content, represented the release of sexual tension. In The Interpretation of Dreams (1899),
Freud developed a psychological technique to interpret dreams and devised a series of guidelines to understand the symbols and motifs that appear in our dreams.
In modern times, dreams have been seen as a connection to the unconscious mind. They range from normal and ordinary to overly surreal and bizarre.
Dreams can have varying natures, such as being frightening, exciting, magical, melancholic, adventurous, or sexual. The events in dreams are generally outside
the control of the dreamer, with the exception of lucid dreaming, where the dreamer is self-aware. Dreams can at times make a creative thought occur to the person
or give a sense of inspiration.

Father

"Dad", "Daddy", "Fatherhood", and "Fathering" redirect here. For the journal, see Fathering (journal). For other uses, see Dad (disambiguation), Daddy (disambiguation), Fatherhood (disambiguation), and Father (disambiguation).
A father is the male parent of a child. Besides the paternal bonds of a father to his children, the father may have a parental, legal, and social relationship with the child that carries with it certain rights and obligations. An adoptive father is a male who has become the child's parent through the legal process of adoption. A biological father is the male genetic contributor to the creation of the infant, through sexual intercourse or sperm donation. A biological father may have legal obligations to a child not raised by him, such as an obligation of monetary support. A putative father is a man whose biological relationship to a child is alleged but has not been established. A stepfather is a male who is the husband of a child's mother and they may form a family unit, but who generally does not have the legal rights and responsibilities of a parent in relation to the child.

The adjective "paternal" refers to a father and comparatively to "maternal" for a mother. The verb "to father" means to procreate or to sire a child from which also derives the noun "fathering". Biological fathers determine the sex of their child through a sperm cell which either contains an X chromosome (female), or Y chromosome (male).  Related terms of endearment are dad (dada, daddy), baba, papa, pappa, papasita, (pa, pap) and pop. A male role model that children can look up to is sometimes referred to as a father-figure.

Friendship is a relationship of mutual affection between people. It is a stronger form of interpersonal bond than an association, and has been studied in academic fields such as communication, sociology, social psychology, anthropology, and philosophy. Various academic theories of friendship have been proposed, including social exchange theory, equity theory, relational dialectics, and attachment styles.

Although there are many forms of friendship, some of which may vary from place to place, certain characteristics are present in many types of such bonds. Such characteristics include affection; kindness, love, virtue, sympathy, empathy, honesty, altruism, loyalty, generosity, forgiveness, mutual understanding and compassion, enjoyment of each other's company, trust, and the ability to be oneself, express one's feelings to others, and make mistakes without fear of judgment from the friend. Friendship is an essential aspect of relationship building skills.

It includes physical, chemical and other natural forces. Living things live in their environment. They constantly interact with it and adapt themselves to conditions in their environment. In the environment there are different interactions between animals, plants, soil, water, and other living and non-living things.
