A player would like to cast the 'Dream' spell on an ancient statue of a petrified hero. Thematically this is wonderful, sure - but does it work by RAW?

Here are possible answers we discussed / lacking backing:

1. **Rule of Cool:** A creative and fun use of the spell! Advances the plot. Not abusable. Why not? Find out if [statues dream of stone sheep](https://en.wikipedia.org/wiki/Do_Androids_Dream_of_Electric_Sheep%3F)
2. **Incapacitated people sleep... why not statues?:** As 5e lists 'petrification' as being *incapacitated* ('no actions / reactions') and is 'not aware of the space around them'. Sleep = 'unaware of time's passage'. Thus all petrified creatures default to a place resembling sleep. Besides, the *Dream* spell is powerful magic - this isn't just shaping biological dreams, it is providing a telepathic uplink between 2-3 creatures for an eight hour span.
3. **Bricks Do Not Dream!** One cannot attain REM-state nor entertain any neurobiological capacity whilst granite. As solid stone, one is not [Han in carbonate](https://starwars.fandom.com/wiki/Carbonite)! Just like an elf that can not sleep, neither can a statue. Even if you successfully cast a *Sleep* spell on such a person-statue, such a creature cannot even entertain this rest-state unless *Greater Restoration* is used.

We are sure that that the first answer is by FAR the most magical, thematic and/or fun (R.A.F.). As a DM, I also fear that the last answer is most logical and/or closest to 'R.A.W.' Still, we would like your collective perspective on this, with thanks.

**Long story short:**  

Is there any ruling, be that a tweet from Mr. Crawford (or other such source), that might suggest that *Dream* can be used on petrified creatures?
