Everyone's imaginations work differently. And that's a good thing! How else could you end up with so many retellings of the same plot? The same can work if you "look" at sounds. Ask for a description from a group of random people, and you'll never get the same description. Therein lies a potential source of inspiration for your work.
Writers are most comfortable holed up in front of their writing machine of choice. However, you can't deny the beauty of the natural world. And I'm not talking about looking up images on search engines, either.
