Weird dream

Just woke up from this weird dream. I’m in a building, in a city I didn’t recognize but I kept saying that it was NY. A huge tsunami, like the one in the movie 2012 hit the city and I was trapped in the building breaking only my nose. While I was in the building (still standing), a white tiger appears out of nowhere and tries to attack me. I manage to defend myself and the tiger falls out of the building. I had a similar dream before but it was a regular orange tiger attacking me.
