Dreaming about a place like Disneyland often signifies a desire for joy, adventure, and nostalgia. Disneyland is a symbol of happiness and childhood, suggesting that you may be seeking more fun and playfulness in your life, especially with your wife.
The specific setting of the store filled with Japanese snacks and items could represent your interests or appreciation for different cultures, as well as a desire to share these experiences with loved ones, like your brother. Your anticipation for your brother to enjoy the products may indicate a wish to connect with him or to share parts of your life that you find enjoyable.
Your brother's indifference to the items, despite being in a good mood, may suggest that while you have certain expectations or hopes for shared experiences, not everyone will share the same interests. This reflects the importance of understanding and accepting differences in preferences among family members.
Overall, this dream might be encouraging you to embrace the joy of sharing experiences with loved ones, while also recognizing that everyone has their unique tastes and interests. It could be a reminder to appreciate the moments spent together, regardless of the activities you choose.
