Nostalgia is a sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations. It is a feeling of warmth and fondness for memories and experiences from earlier stages of life. Nostalgia is often triggered by familiar sensory stimuli such as music, smells, photographs, or objects that evoke memories and create a longing to return to those past times. It can be a powerful and comforting emotion, as it allows individuals to reminisce on positive aspects of their past and find solace in those memories.
