I often dream in color and i am always in a large house or building with lots of people. Does this signify any?

The scenerio and cituations of my dreams change but the setting is often familiar, lots of random people and people i know and love. And i am always in a big house, or building, or public place with lots of people. I have also had dreams that i am supposedly at home but my house looks totally different or i will be at my home and the dream will switch to me being somewere ele. Does this signify anything??
