You can start to do this be reviewing the various schools of interior design and deciding which one of them most reflects your philosophy of beauty and comfort. The main ones are Modern, Oriental, Gothic, Roman, Greek and Egyptian.
The Gothic theme makes wide use of black and includes eccentric touches such as gargoyles and exotic curtains and such. IF you want to make a statement in your bedroom, this style will surely do it.
The Greek and Roman themes also have a lot in common, since it is said that Roman design is based on the Greek but also improves upon it. Large columns and open vistas mark this style, so it is really only possible if you have a large bedroom space.
If gold is your color, Egyptian is your theme. The liberal use of lush colors such as gold and fabrics such as silk and tapestry will make a room look like Cleopatra's court. For an added touch, use stone tablets with hieroglyphics or depictions of ancient Egyptian gods.
Picking style or period theme is a good way to get started on the best way to re-design you bedroom. There are many other ways to go, but if one of these reflects your personality, go for it!
