So, I only saw a single episode of this during my childhood - 10 or more years ago I had guess - where there is a group of children whose father programmed a game and they ended up in the game and can't get out. Inside the game they have a base inside a tree house and I believe they were able to communicate through the computer screen with people inside the RL house.
Yeah, I know this might sound quite vague, but it was the very first encounter I had with VR and kept me fascinated for ages and might be one of the reasons I got 'into' VR, so would love finding it back.
