I guess this must be a 70s or early 80s movie. A couple who had lost their only child travels to the countryside, to an old house, which belonged to their family. On their way they have an accident, crashing the car into a tree. They walk to the house. One of them starts hearing strange noises and voices and then begins to see ghosts in the house, of their family ancestors who had lived there. At the end, both of them can see the ghosts, they become terrified and decide to leave the place. When they reach their crashed car, they see themselves dead inside, and finally understand why they could see the ghosts, they were dead already. I have tried and tried to find out the title of this movie, no one recalls having seen it
Any help would be welcome
Thanks a lot
