Just thought of one more from my childhood that I’ve been looking for.
This was on TV, probably late 80s, and I believe it may have been part of a TV series, possibly an anthology series like Twilight Zone or Tales from the Darkside. The setup as I remember it is that a girl travels back in time, for whatever reason, and brings her Walkman. She befriends another girl, but someone else afraid of her Walkman accuses her of witchcraft, and she must escape back to modern time before she gets burned at the stake.
Suggestions much appreciated as always. Cheers
