Another House Dream

Last night
I had a dream that I was taking a walk.
I was walking
in the city where I used to live.
I happened to pass the house
that I sold about five years ago.
The people who bought the house
had lost it to a foreclosure.

It just so happened that
a real estate agent
was showing the house
to someone as I was passing by.
As the person left
I asked the real estate agent
if I could have a look at the house.
He was glad to show me in.

The house had a camper in the living room.
He explained that
that was because the previous owner's family
needed more bedrooms.
The camper was their son's bedroom.
He said the daughter had her room in the basement.
I told him that I was the previous owner of the house
and I knew that the house had no basement,
just a crawl space.
He then opened a trap door
and led me down the stairs to the basement.
It was a finished basement,
only the area that was bedroom was finished.

We then went back upstairs
and I noticed that the furnace
was not only in a different place,
there were two furnaces.
He said that it was to heat the other camper.
He then opened a door
that led into another camper.
It was annexed to the house,
but not visible from the outside.
I couldn't figure that out. . .
It was like a hidden room.
The second furnace was to heat this
camper, this hidden room.

He said the house was selling for $40,000.00
I asked if that was for a 30 year mortgage.
That just didn't seem right to me.
The monthly payments would be so small.
I seriously considered re-buying the house.

So many dreams about hidden rooms. . .
What does a hidden room mean?
A hidden basement?
And why would I dream about a house
I sold several years ago?
What does $40,000 mean?
Is it a symbolic amount?
And 30 years?....
