I'm stumped trying to remember a film, so I guess it's time to throw myself on the mercy of this thread.
I believe this was a sci-fi or fantasy themed movie from the '80s or '90s. It might very well have been a prominent film. My problem is that the scene I'm remembering was not important, just a little futuristic "coloring" that wasn't vital to the plot at all, and I can't connect it to any movie in my memory. In the scene, a woman is tucking a little boy in to bed at night. In doing so, she switches on a sort of "dream program" for him, which is heard offering a selection of little-boy friendly dream scenarios, like an outer space journey, a cowboy adventure, etc.
Sound familiar to anyone? Thanks eternally for your expertise!
