Right now I only remember the end of the dream.
Mostly I spent time in the basement of this house, but I went upstairs and found that the floor had sagged in places leaving a gap under the wall, which was obviously not going to be good for air conditioning efficiency or mosquitos. But then I looked around and realized this entire section of the house was falling apart, like an old barn, and it was the part that we treated as more of a porch anyway.
So maybe we'd just rebuild that whole part. Or just leave it.
