The room of my dreams is light, large and with big windows. It is cozy and comfortable too. I think the room will make me happy, if the colour of the walls will be bright, maybe yellow, white or pink, but not gray, because this colour depresses me and it is boring. And I dont want to have red walls in me room because this colour is too much powerful for me and hinder me to rest.Of course I dream about big room because big rooms make me feel freedom and i like this feeling. I want to have a furniture : the table, the cupboard and the bed, these are most important things in any room.I hope some time later I will create or buy a room like this.
