This website is actually part of a bigger one called DreamResearch.net where you can find interesting info such as some investigations into what children dream.

It seems that there are some "cognitive prerequisites for dreaming", which are mostly developed around the age of 5-7, which might explain your dreams being so crazy and full of colors, as in those ages you are still developing "the ability to produce mental imagery" and "narrative skills".
