Rooms Full of Soil

I dreamed I was walking down a covered walkway.  On the one side was an older house from the 60s.  On the other side was a cinderblock building with cheap doors in it, like a storage unit where someone had cheaped out and used interior doors.  I opened one of them.  the doorway was full, top to bottom, with soil.  I scraped at the soil and it fell off, revealing that it was just an inch layer of dirt held in place by floor to ceiling chicken wire.  But the rooms behind the other doors were not like that, they were just dirt.
