How do you get points in the Pokemon dream world?

Question

I have only been to the Dream Park, Sparkling Sea, and the Icy Cave.

Answer 1

Watering another player's Berries= 10 Points

Winning a minigame	       =          20 Points
Gain a Dream Pal	=                 30 Points
Log in to the Global Link       =     50 Points
