Today, I felt the same as if I had been in the past when I heard my favorite song from the distant 97. It's not what we see that matters. What matters is what we feel. Only what is felt and experienced is never forgotten, this is the main component of memories.
Music has a way of taking me back sometimes too. Have you every heard an older song that you really connected with and have no idea why? I heard Haydn's String Quartet in F Major "Serenade Quartet" for the first time and it was so familiar and gave me such a good feeling. Maybe it was from a past life? I'm not sure but it was a magical experience.
