Dreams often use symbols and feelings to convey messages or insights about our waking life. In your dream, the names "Akari" and "Asahi," which are Japanese and can mean "light" and "morning," respectively, may suggest themes of hope, new beginnings, or clarity.

Laying in a field of lavender can symbolize tranquility, peace, and healing. Lavender is often associated with calmness and a sense of well-being, indicating that you may be seeking or experiencing a sense of relaxation in your life or relationship.

The red and orange setting sun can represent change, transformation, or the end of a cycle. Sunsets are often viewed as a time for reflection and can symbolize the beauty in transitions, perhaps indicating that you are moving from one phase of your life to another.

Overall, this dream could suggest that you are in a peaceful state with your boyfriend, and there may be new beginnings or changes on the horizon that will bring clarity and light into your life. It might be a good time to reflect on your relationship and any upcoming transitions you may be facing.
