Dream interpretation can be tricky, and the service they provide her on the website is like the handbook you get with a tarot deck, it's just to give you a push in the right direction.
It is suggested with things like this that you find your own meaning, as everyone thinks differently, therefore everything holds slightly different meaning to every one. I do not suggest taking the meanings on this website too seriously, they are just there to give you an idea as to how to go about interpreting your dreams.
Not to mention, some dreams tell stories, and chopped up symbolism will give you a story like, "The cow hopped on one leg over to the orange bulldozer and sang happy birdwatching."
That, tells you nothing.
Dreams apply to you personally, as they are your subconscious reflecting what's in the back of your head. Dreams are what you're thinking about when you're sleeping, so what you dream about, has a combination of literal, and symbolic significance, keep that in mind.
