What is dream?

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:

    Holland is a dream, Monsieur, a dream of gold and smoke—smokier by day, more gilded by night. And night and day that dream is peopled with Lohengrins like these, dreamily riding their black bicycles with high handle-bars, funereal swans constantly drifting throughout the whole country, around the seas, along the canals.
    Albert Camus (1913–1960)

    Look not too long in the face of the fire, O man! Never dream with thy hand on the helm! Turn not they back to the compass; accept the first hint of the hitching tiller; believe not the artificial fire, when its redness makes all things look ghastly.
    Herman Melville (1819–1891)

    I turn my gaze
    Back to the instruction manual which has made me dream of
    Guadalajara.
    John Ashbery (b. 1927)
