I went to my friend's Mom's wake - loved the celebration. Other than that, never participated in a nine-night or Dead Yard. But I do know that traditionally Jamaicans are buried in their yards. These days there's a few hoops to jump through to do this - my friend and neighbor was buried in her yard just a couple of years ago.

Several times while on the road we've passed lavish funeral processions - a truck and band are hired and play joyous music at the front of the procession from the church (funeral) to the yard or cemetary (burial). The coffin is lifted and the pall bearers dance with it....very similar to a New Orleans style funeral.

Years ago a friend there who is an artist and was close to the deceased had the great honor of painting in the grave. This is done so the deceased stays where they are and doesn't come back as a Duppy to haunt anyone. I forgot what imagery she said she painted but it was very signficant, each painting on each wall.

When I was in Jamaica this last time I visited the cemetary in Redground where the grave sites are lavishly decorated and the tombstones are brightly painted, again with signficant imagery and words. On several the deceased's dates were written as "sunrise" and "sunset". I took that cue when we put together a memorial slide show for my friend who just succumbed to Cancer - at the end of the film we notated his dates just that way.

Nine nights
From Wikipedia, the free encyclopedia
Nine-Nights also known as "Dead Yard" is a funerary tradition practiced in the Caribbean (primarily Jamaica, Guyana, and the Dominican Republic). It is an extended wake that lasts for several days, with roots in African tradition. During this time, friends and family come together to the home of the deceased. They share their condolences and memories while singing hymns and eating food together. In the old days, the nights were calm and reserved for the most part - but that tradition has changed with the times. Today, these gatherings resemble parties much more than they resemble wakes (though this is not true for all “nine-nights”).
Nine-Nights are no longer a time to mourn but a time to celebrate since the loved one is no longer suffering in life. When friends come they do not come with just condolences they come with food, drink and music; this is after all a celebration. True to its name this celebration lasts nine nights and days with the ninth and final night being the night before the church service (Though some modern Islanders only celebrate for seven days and seven nights). On the ninth night the family prepares the food for all who come. As tradition has is on the ninth night it is believed that the spirit of the deceased passes through the party gathering food and saying goodbye before continuing on to its resting place. Out of all the nights this night is the most revered since it is the end of the celebration. Stories about the deceased and the fondest memories are shared, along with prayers. Games, such as Dominos, are played as well as singing hymns, which is also done on the other nights as well.
On the ninth night a table is set up under a tent with food for the loved one, though no one is allowed to eat from it before midnight because it is believed that this is the time that the spirit passes through. Along with the food are drinks, most often Jamaican rum with no less than 100 proof. The types of food on the table can vary from one celebration to the next, but typically fried fish and bammy are the main foods on the table. This time is very important to the family because it gives them time to celebrate the life of their loved one and to be able to say their goodbyes.
Traditionally on the ninth night of the deceased's death their bed and mattress are turned up against the wall, in order to encourage the spirit (Jamaican patois "duppy") to leave the house and enter the grave.
