Dreaming of visiting the childhood home is a very common dream that allows you to explore and transform the patterning you adopted from the family. Consider the aspects that make the home different from what you remember. These differences are important in recognizing the ways you are different from your family. You are a unique variation of the line you carry forward.
The rooms represent areas of your life that are changing. Since the house represents your 'inner architecture, a symbol of the ideas and aspects of your inner world, visiting the childhood home is a way of re-evaluating some of the belief structures adopted at that point in your life. For example, the front yard may be different, as you test out new ways of expressing your uniqueness in social exchanges aside from what you were taught. Often you will be in the kitchen, since being fulfilled is an important aspect of wellness - and self acceptance often requires that you 'nourish' yourself with the positive reinforcement that could have been missing in childhood.
