Yep, dreads do grow; they grow at the same speed your normal hair grows. Even though it seems like they are growing slower because the hair has to spiral and twist and knot. So it seems like dreads are growing ¼ the amount that normal hair grows. The hair does not grow into the dread unless the roots of the dread are locked up. So it is very important to lock the hair at the root, you can use the clockwise rubbing method to do this.
