Thou comest as the memory of a dream,<br>Which now is sad be — Memory | Quote

"Thou comest as the memory of a dream, Which now is sad because it hath been sweet."

Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. Memory loss is usually described as forgetfulness or amnesia.
