The Galactic disc is the region of the Milky Way Galaxy where our Solar System resides. It is crowded with stars and clouds of gas and dust, and also a concentration of elusive dark matter. #-># taken from here.

Where there is matter, there is about 5 times more dark matter. While they do not interact physically and chemically, you can say that they are simply gravitationally attracted to each other.

Dark matter also helps shape stars; imagine trying to push a heavy cartload of rocks, it would be very difficult or even impossible. Now imagine there are 5 other people to help you- it would be much easier and physically feasible.

Note: Although the study of dark matter is very exciting and insightful to us, the nature that dark matter and energy does not interact with light makes them difficult to study; after all, they are hypothetical.
