Ok so here's my take on the "house connected to shopping mall via secret passage"


A house represents a "dwelling or abode for the spirit" , the "secret passage" as opposed to an open one represents a personalized "access" to a shopping mall which is a place where "various items necessary to make a living are made available" .

Take together that means that wherever your spirit resides you will have access either to information or communication to your spirit necessary to further yourself.Since it's secret it's not readily available to most.
