Bathtub in the Road

No, I am not making this up. In traffic reports one recent morning there was word of a rush hour delay because a bathtub was in the road. I've been thinking about it all day. What does it mean to be blocked on your way by a bathtub in the road? It's a powerful metaphor for something. I just don't know what.

This slice of real life comes on the morning after a dream I had. I was digging up a broken sprinkler valve in the front yard. Because the water had been flowing freely it had carved an underground chamber. I was peering into the hole trying to decide how big it was when I saw a light. I looked deeper and saw that the hole expanded into a large cave with smooth concrete floor that ran from my yard to somewhere under the street. Then I saw a man, kind of Mexican looking. I yelled (or tied to yell in that dream-paralyzed state) at him to get out of there and he ran off deeper into the cave. I suddenly knew how they were getting access to my house! Then I woke up.
Perhaps the Mexican living under my street had something to do with the bathtub in the road.
