Dream

Dreams are successions of images, ideas, emotions, and sensations that occur usually involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not definitively understood, though they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recorded history. 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.

Liberty

Liberty, in philosophy, involves free will as contrasted with determinism. In politics, liberty consists of the social and political freedoms enjoyed by all citizens. In theology, liberty is freedom from the bondage of sin. Generally, liberty seems to be distinct from freedom in that freedom concerns itself primarily, if not exclusively, with the ability to do as one wills and what one has the power to do; whereas liberty also takes into account the rights of all involved. As such, liberty can be thought of as freedom limited by rights, and therefore cannot be abused.

Philosophy

Philosophers from earliest times have considered the question of liberty. Roman Emperor Marcus Aurelius (121–180 AD) wrote of "a polity in which there is the same law for all, a polity administered with regard to equal rights and equal freedom of speech, and the idea of a kingly government which respects most of all the freedom of the governed." According to Thomas Hobbes, "a free man is he that in those things which by his strength and wit he is able to do is not hindered to do what he hath the will to do" (Leviathan, Part 2, Ch. XXI).

Starting out in 1963 with the group The Wailers, he forged a distinctive songwriting and vocal style that would later resonate with audiences worldwide. The Wailers would go on to release some of the earliest reggae records with producer Lee "Scratch" Perry.

After the Wailers disbanded in 1974, Marley pursued a solo career upon his relocation to England that culminated in the release of the album Exodus in 1977, which established his worldwide reputation and produced his status as one of the world's best-selling artists of all time, with sales of more than 75 million records.Exodus stayed on the British album charts for fifty-six consecutive weeks. It included four UK hit singles: "Exodus", "Waiting in Vain", "Jamming", and "One Love". In 1978 he released the album Kaya, which included the hit singles "Is This Love" and "Satisfy My Soul".
