I've been described as one of these.  

 An "old soul" is a term used to describe someone who seems wise and mature beyond their years, often characterized by a deep understanding of life and a preference for things that older people might enjoy.  

Here's a more detailed look at what the term "old soul" often implies:

• Wisdom and Maturity:

  People often describe someone as an "old soul" because they exhibit a level of wisdom and maturity that is not typical for their age. 
• Deep Understanding of Life:

  Old souls are believed to have a deeper understanding of life's complexities and nuances, often reflecting on the bigger picture rather than focusing on trivial details. 
Appreciation for the Subtle:
They often appreciate the finer things in life and have a keen sense of observation, picking up on the subtle nuances of human behavior. 
Meaningful Connections:
Old souls are often drawn to making meaningful connections with others and showing appreciation for the people around them. 
Desire to Learn:
They have a strong desire to learn and explore different subjects, viewing learning as an essential part of life. 
Focus on the Bigger Picture:
When faced with challenges, they tend to see the bigger picture and don't get caught up in the details. 
Potential for being misunderstood:
Some people may find it difficult to understand or relate to old souls, who may seem a bit "weird" or different from their peers.
