Complete Dictionary of Dreams

by Dr. Mıchael Lennox
The house as a symbol is reflecting your sense of self at the time of a dream.

The porch is outside of the house, but is still connected to it. In this way, it relates to the part of your consciousness that can maintain a sense of identity but share that identity with others in a social way. This interdependent sensibility is reflected by a dream that involves the porch of a house, so the state and condition of the porch is reflecting how you are maintaining your sense of self, but still interacting with the world.
