The white horse and golden eagle are fighting. The eagle used its talons and slashed the horse's muzzle. A monstrous voice laughed and it sounded like it came from underground.
Most of the barnyard animals were trying to kill Percy. The other just wanted food.

There was a city behind him ( not NY ) and there was a huge storm and palm trees in the distance. Two men were fighting they both had long hair and beards. They each wore flowing Greek tunties one blue and one green. Every time they connecting a lighting flashed and the sky grew darker.

Someone was trying to pull him into the darkness but then soon realized he was pulling someone out from that darkness.
