I'm looking for a film made in the early 90s (maybe even 80s). Seen it in my childhood:
There was a girl living in a future where everybody basically lives in virtual reality. She accidentally connects to her mom's 'dream' where she sang opera with some sort of a Pavarotti guy. Then she somehow finds herself in a post-apocalyptic world where people live underground and there's some sort of a sacrificial mincer/fan. There was also a forbidden polluted zone and some guy pursued the heroine there. Eventually it turns out the cyberworld is run by the girls's dad, who retires and she takes his place.
