I'm trying to remember this segment. A woman has a dream or premonition of visiting her father/grandfather/uncle's funeral, but it's just her and him attending and talking by his casket?

Does this sound familiar to anyone? Thanks.

I think you are referring to the Catherine Webb segment?

It's not a father grandfather uncle - it's an old lover. She has a dream where he comes to her to let her know he has died and it is set in an empty church infront of his casket.

It's the last portion of the first segment here:
