Dream

Dreams are successions of images, ideas, emotions, and sensations that occur 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. Scientists believe that, in addition to humans, certain birds and the majority of mammals also dream.

Famous quotes containing the word dream:

“yet when all is said
It was the dream itself enchanted me:
Character isolated by a deed
To engross the present and dominate memory.”
—William Butler Yeats (1865–1939)

“Dream is not a revelation. If a dream affords the dreamer some light on himself, it is not the person with closed eyes who makes the discovery but the person with open eyes lucid enough to fit thoughts together. Dream—a scintillating mirage surrounded by shadows—is essentially poetry.”
—Michel Leiris (1901–1990)

“We too are ashes as we watch and hear
The psalm, the sorrow, and the simple praise
Of one whose promised thoughts of other days
Were such as ours, but now wholly destroyed,
The service record of his youth wiped out,
His dream dispersed by shot, must disappear.”
—Karl Shapiro (b. 1913)
