Well...I am not really a 'religion' follower of any kind, but my Dad's side of the family is Catholic.
It is traditional to have a Wake/Viewing the night before the actual service. People get together and view the body. It is usually pretty quiet. No one wants to really speak up and say anything but everyone makes a point to say how 'good' the deceased looks. There are usually 'memory boards' hanging up which are just boards with pictures of the deceased throughout their life hanging on them.
Usually they are buried with pictures and meaningful momentos from their life in their caskets with them. Lots of flowers are sent to the funeral home in memoriam of the deceased.
They did the rosary at a couple funerals I have been to, during the viewings.
Then the next day in the morning is usually the service at a church. People read eulogies, bible stuff is read, Amazing Grace is usually sung...then they are taken out to the cemetary where they are interred. The family and close friends usually get together for a dinner afterwards to celebrate the deceaseds life.
I have also been to funerals on my Mom's side though for my Grandparents that were nothing more than a closed viewing for the family, no service at all, and they were interred the very same day at a very private service. Very few words were read, and that was it.
Death seems to be very taboo. No one likes to talk of it (atleast that I know of). People find it to be depressing and sadenning, which it is, but it is also a time of celebration. They are passing on to a better part of their being, and are no longer here hurting and suffering with the rest of us.
As far as the healing process goes, many people just try to 'live their life' like 'normal' after someone close to them has passed. Trying to ignore the grieving process is usual, and many times people are forever 'changed' because they don't know how to cope with their loss.
But...that is just my family, what I think, and my opinions/views. This is coming from someone who wanted/wants to be a Mortuary Science major...I would be the one embalming, reconstructing, and dressing the bodies as well as making the arrangements and working with the families.
I still may go to school for this after my Education degree is finished...
