If you dream of following someone, it could mean that you desire to be in the company of that person. In real life, someone you know is moving away or is doing something, and you don’t want changes. The next best thing you can do is to follow that person.
Another interpretation of following might be your subconsciousness telling you that you have been doing too much of it lately. Maybe its time for you to think about how you can do things your way, or strike out on your own.
