Dreams about seeing an old friend, especially one who appears younger and happier, can symbolize nostalgia and a longing for the past. This may reflect your feelings about your own life or changes you've experienced since you last saw this friend. The fact that she looks pretty and is adorned with a long white lei suggests a sense of celebration, purity, and joy.

The lei can also represent a connection, love, or friendship that transcends time. It could indicate that you cherish the memories you have with this friend or that you're seeking to reconnect with aspects of your past that brought you happiness.

Consider what this friend represents to you and how you can bring those feelings of joy and youthfulness into your current life. It might be a good time to reach out to old friends or revisit activities that once brought you joy. Reflect on what aspects of your past you can celebrate or integrate into your present.
