Take a few deep breaths and let them out slowly.
I can't come and help since I'm at work. But, one very important tip, do not catch your opponents as ghosts. They do not count toward your total.
Also, make sure to shake the coffins when you are a ghost and your opponents can't get to you yet. Stay fairly near the coffins.
Your oppenents need to make sure that they keep catching all of their ghosts and shaking the coffins when there isn't any out.
You really need to be lucky enough to get rooms with several coffins close together instead of spaced far apart.
That's all I can think of at the moment.
GL and try to keep calm.
