Has anyone been to nighmares ghost sories haunted house?

I've seen some movies about ghost stories and haunted house, but to me it is unbelievable. Very few times I dreamed of ghost but not that much, I cannot describe much because it was hazy and I cannot see what its all about. Zombies, ghost as described in the books and the movies. Maybe that is an aftermath of what Ive seen in the movies. But although i believe on them, I havent seen one.
