Ever since I was a teenager, I've had a particular scene stuck deep in my image memory but I don't have much else to go by. I was hoping to figure out what movie or TV show it was from.

All I can remember is that these two characters (I think they are siblings) are near a large estate/house. In one scene, they're outside talking on a swing - either in or near a gazebo. The scene takes place at night, and it was rather gloomy or cloudy. They walk back to the house, and up a long flight of stairs to a narrow mansion-esque porch. In the following scene, they're standing next to an armoire in the foyer at the foot of some stairs.

I keep thinking this was a spooky/halloween kids movie or TV special. Maybe it was an episode of Are You Afraid of the Dark, Goosebumps, Big Wolf on Campus or one of the other witchy/occult/horror shows aimed at kids/teens; I really don't know, but I was hoping it might trigger someone else's memory and I could solve this mystery!
