Dreams come preloaded with a guidance system. They know the fastest way to bring themselves into reality.
They also come with more than one path. I say this, because the fastest way is "as the crow flies" which means it is usually the harder path to take. Most of us would prefer the shortcut. The Staples "easy button".
It might be that we are not confident of our ability to take that harder path. I am a huge "Lord of the Rings" fan. When Frodo and Samwise go forward on the journey with just the two of them, they are definitely taking that hard path. I always thought that if the Eagles could rescue them at the end when the lava was coming to kill them, why couldn't they have dropped them off at the mouth of the cave?
The reason of course is that Frodo and Samwise needed to learn many things to enable them to win over the power of the ring and truly destroy it. Without those lessons, the ring would have won.
So it is with us. The harder path will teach us what we need to win through to the dream and be able to handle the changes that acoomplishing the dream will make in our lives. If we take the easy path, the shortcuts, then we may not have the strength of character that has been tested and forged in the fire. Without this, our ultimate dream may not be able to make it into reality.
So even when the dream points us in a direction that we think is too difficult, that we don't think that we possess the courage or skills to make happen - it is in our ultimate best interest to pull up the big girl/boy panties and go for it. I always tell myself, that if the divine gave me this dream, then he also must have given me the skills needed to make it happen. So follow the breadcrumbs and storm the castle!
