what is the meaning behind the "alterna" PV?

[jojo-chen]

the PV consist of:
1. an electric fan (with red ribbons)
2. Scary clowns
3. White Ayu
4. Dolly Ayu
5. A letter : "Congratulations, YOU ARE THE STARS" -omedetou, anta wa sutaa-
6. Scary eyelashes (black feather)
7. guitar played by the clowns
8. "Beautiful Trap" -0-;
9. Singing Machines
10. Copy factory for the singing machine
11. An eyeball inside ayu's mouth
12. garbage dump

anybody help me plz, I'm just soooo curious! Is that all was symbols? or just a visualization of ayu's life? (from an ordinary girl becoming a star then sing without limitation, feel trapped then angry then "dumped")--> my opinion, plz help me with this one.. arigatou..
