Dreams often have personal symbolism, and the elements you've shared can provide insight into your feelings and experiences.

1. Akari Asahi: This name could represent light ("Akari" means light in Japanese) or a new beginning ("Asahi" can mean morning sun). This might suggest a desire for clarity or illumination in your life or relationship.
2. Field of Tulips: Tulips are often associated with love and passion, as well as beauty and renewal. Laying in a field of tulips with your boyfriend suggests a feeling of comfort, love, and perhaps a flourishing relationship.
3. Red & Orange Setting Sun: The colors red and orange are often associated with warmth, energy, and passion. A setting sun can symbolize the end of a phase or a moment of reflection. This could indicate that you're contemplating the transitions in your life or relationship, embracing the warmth and beauty of these moments.

Overall, your dream seems to reflect a deep connection and positive feelings toward your relationship, with an emphasis on new beginnings and the beauty of love. It may be beneficial to consider what new opportunities or changes you are hoping for in your life or relationship moving forward.
