This is very possibly a dream I had as I would have been around 4-5 at the time.
All I can remember is some kind of statue head attacking a city with people running away. Theres a black female cop who gets picked up and the statue monster bites off her head. I immediately turned off the TV and ran out of the room.
That's it unfortunately. Like I said I very possibly dreamed it, but I feel like I ran out of the room towards a parent right after.
There's this weird movie called Zardoz, and Zardoz is a giant statue head, but I think it takes place in medieval times, so it would be unusual if there was any kind of city.
