Yes it is possible. Have you ever had an imagination or a dream? A mere thought can be a concept. In fact, most concepts are thought of first before writing it in stone. This is foundation of creativity. Think of a story that you read. The author of that story had thought of some idea or plot that the people or characters have played a part in using mental images.
As for the words, they are physical records of the thought process. A physical form that one can see using the eyes. Whereas imagination is something one sees using his/her mind.
