The only thing to do is to read. Keep reading. Just wander around randomly, gobble it all up, and chew on it. Roll it all around in whatever that thing is between your ears. I've got one too (albeit dysfunctional): There's no shame in it. We've all got one. Sooner or later something will reach out of the fog and grab you. If it refuses to let go, you're all set. It might be the name of some loathsome popkultur monstrosity in Random Nodes, which reminds you of a song he sang; all of that may sit there and ferment for an hour, and suddenly burst forth into something genuinely weird.
Or it might be a line about tree sap in a Webster 1913 entry, which for some reason reminds you of the Faroes or some place like that. Or it might be something else entirely. The thing is to keep your eyes open and don't worry about it. Something which needs to be written is looking for you. Be there to let it in.
