Dreams often incorporate elements from our waking life, such as people and emotions, and can be rich with symbolism.

Hearing the names "Akari" and "Asahi" might suggest themes of light or brightness, as "Akari" can mean "light" and "Asahi" can mean "morning sun" in Japanese. This could symbolize a new beginning or a sense of hope in your life, especially since you were with your boyfriend in a serene setting.

Laying in a field of peonies, which are often associated with prosperity, good fortune, and happiness, indicates a sense of comfort and emotional fulfillment in your current relationship. The red and orange colors of the setting sun may symbolize passion and warmth, signifying a deep emotional connection.

Overall, this dream could reflect a positive phase in your relationship, highlighting feelings of contentment, love, and the beauty of shared moments. Consider what aspects of your relationship or life you feel particularly hopeful about, as this dream might be encouraging you to embrace those feelings.
