Bucks Dreams

I’ve been having a ton of dreams that I can not remember the past couple days.  Here is the only one I could make out.

I was in a store. More of a hardware store and in line.  I do not think I had anything in my hands.  The guy in front of me was the older, friendly, talkative type.  He had a handful of these little plastic items, much like a relay switch.  

He was telling me that he was the mechanic for heavy machinery for some company and 5 units did not work right.  He said, “When you push down it goes up and when you pull up it goes down. Reverse!  … and thats not very good in this business”.  

I just said, “I  bet not” and tried to ignore him.  I woke up.

What does it mean?!
