Dream Points

Thing is, i only got one random island near me. Is that normal?

Yes. Once you request a person to be your friend and they accept, a rainbow bridge will bind the two of your islands together. Until then you will only ever have that one random island. After that point their island (and any subsequent islands of any future friends) will always appear alongside one random island. I don't know if all the islands of your dream-friends will appear at once, however.
