Animal Crossing: New Horizons now has a Dream feature that allows players to visit other islands without having to go to the airport. The other player doesn’t even have to be online. (You need a Nintendo Switch Online membership to use Dreams.)
That is, you cannot buy items or pick fruit if you come to visit through a dream. This is mainly to make it easier for you to share your creative vision with others. As a bonus, you can invite people over without worrying about them destroying your house or trampling on your flowers.
Luna, a tapir, will help you sleep.
How to upload your island
If you are lying in a bed at home, you will be asked if you want to sleep. Say yes and you will see Luna who will offer to help you. To unload your island, say “I want to share a dream”.
Once you’re connected to the internet, she’ll give you a dream address code to share that represents your island. Your dream address will appear in your passport and on your card, so don’t worry about saving it if she tells you the code first.
Please note that you can only charge your island once per day.
How to visit other islands with dreams
After talking to Luna for the first time, you can sleep in any bed at home. Once you lie down, the game will ask you if you want to dream. Choose Yes and you will be enveloped in a purple mist before seeing Luna again. Tell him you “want to dream” and he will ask you for a dream address to enter. Once you enter the island code, you will wake up from your bed in front of Resident Services on the island you wish to visit. As a reminder, you won’t be able to do much more than take in all the sights. But it is okay !
When you’re ready to return to your own island, simply lie down on the bed.
