Any ideas to decorate my REALLY small ,bedroom i have pictures?

To reiterate someone else, painting your existing furniture to match your bed would be great--use an all purpose primer first. Baskets will become your best friend. You can use two matching baskets to tuck your dvds in on your nightstands. Baskets will help with decluttering and reducing the amount of small hits of colour. Another way to integrate your posters into your design is to frame them with matching white frames and perhaps hang them over your bed or beside the window. Nice bed choice.
