Hi
You are in the wrong forum - post this in the V V 3 forum. However, maybe I can help?
Put a villager on the dial and slowly move it clockwise. As the villager moves it, you will see a beam of light come in - just leave it a second in each position until the beam of light eventually will shine in...that's what you need.
It will bring the ghosts...after that, anytime you put a villager near that spot, the ghosts will appear.
Hope this helps. There are many cheat sheets out there for all the villagers
