Dreama

This name derives from the Old English “drēam,” meaning “joy, pleasure, gladness, delight, mirth, rejoicing,” probably related to the Old English “drēag,” meaning “spectre, apparition, illusion.” In turn, this name derives from the Proto-Germanic “*draugmas,” meaning “deception, illusion, phantasm” (dreams are not real, but it’s just an imagination). Dreams are successions of images, ideas, emotions, and sensations that occur involuntarily in mind during certain stages of sleep. The content and purpose of dreams are not definitively understood. However, 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.
