Your dream gets sharper as you get closer. Blurry from far away is completely normal.

Not being able to describe exactly what you want is a feature of distance, not a sign you lack direction. Detail arrives as you approach, because most of it is only visible from nearby. Waiting for total clarity before moving keeps you at the range where clarity is impossible.

Move toward the rough shape and expect the picture to resolve on the way. Take the next step that is clearly in the right direction even if the destination is vague. Check again in six months and notice how much more of it has filled in.
