Some people have a "dumb supper" for Samhain. It's a ritual meal for the living and the spirits, where the living folk don't speak at all the entire time, communing with Spirit for the entire meal.
*nods* Yes, and many times I've heard that you should serve "dark foods". For example, dark breads like pumpernickle, dark fruits like red or black grapes, plums, blueberries, red meat, pomegranates, dark cheeses like sharp cheddar, etc. I've been to dumb suppers where the feast was created in this way - it was very beautiful.
