If something or someone is followig you in a dream, then there is very likely something you are having a hard time putting “behind you” in waking life. Is there a grudge you need to let go of? An issue you haven’t dealt with properly? A reputation you can’t get rid of?
If you are following something or someone in a dream, then that thing or that person represets something you want to obtain in real life. Are you wanting to follow in someones footsteps?
