Disappointed by dream traveling to other islands- how do you get fruit?

I added Nintendo online account specifically so I could travel to dream addresses so I could collect more fruit for my island. I was so disappointed after doing my first visit when I realized things you take at the dream addresses don’t really come back with you 🤦‍♀️I don’t understand how to get non-native fruit then!?!? I have my native fruit, my “sister fruit” from a random island visit and coconuts but I want all of the fruit so I can make different recipes and crafts that call for fruit I don’t have. What am I missing?
