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.

Head

A head is the part of an organism, which usually comprises the eyes, ears, nose and mouth, each of which aid in various sensory functions, such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head.

Human head

The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). The skull can also be described as being composed of the cranium, which encloses the cranial cavity, and the facial skeleton (includes the mandible). There are eight bones in the cranium and fourteen in the facial skeleton.

A Head Full of Dreams

A Head Full of Dreams is the seventh studio album by British rock band Coldplay. It was released on 4 December 2015 by Parlophone and Atlantic Records, with a markedly different style and sound from its predecessors. It is the second album by the band in North America on Atlantic, after Coldplay were transferred from Capitol Records America in 2013. For various songs on the album Coldplay collaborated with Beyoncé, Noel Gallagher, Tove Lo, Khatia Buniatishvili and Merry Clayton. The album was produced by Rik Simpson and Stargate. Coldplay have also revealed that the album features a sample of the U.S. President Barack Obama singing "Amazing Grace" at Clementa C. Pinckney's funeral on the track "Kaleidoscope".

The album received generally positive reviews from critics. It became the band's first album not to debut at number one in the UK after being held off the top spot by Adele's 25, however it topped the chart on 12 February 2016 following exposure from the band's Super Bowl 50 appearance.

After they formed under the name Pectoralz, Guy Berryman joined the group as a bassist and they changed their name to Starfish.Will Champion joined as a drummer, backing vocalist, and multi-instrumentalist, completing the line-up. Manager Phil Harvey is often considered an unofficial fifth member.

Their next release, X&Y, the best-selling album worldwide in 2005, was met with mostly positive reviews upon its release, though some critics felt that it was inferior to its predecessor.
