Dreams are highly personal and subjective experiences that occur during sleep and are still largely unexplained by science, with little scientific evidence to support definitive meanings.
Harvard Health notes that sleep quality is crucial for overall health, affecting various bodily functions such as mood, muscle tissue, brain function, and the immune system. While it is easy to understand the purpose of sleep, it is more difficult to explain why we dream and how to interpret them. Dreams occur during sleep and consist of thoughts, emotions, events, people, places, and symbols relevant to the dreamer. While scientists understand what happens physiologically when people dream, there is still much to be studied about what happens psychologically. Different cultures have ascribed meaning and importance to dreams, but there is little scientific evidence to support definitive meanings. Dream interpretation is highly personal and subjective, with dreams being a conversation with oneself on a subconscious level.
