the mule

in this dream i am a courier for some party but don't know what i'm ferrying or why except that it involves 2 full plastic garbage bags 1) for the pick up 2) for the exchange but all i do is for my boss who seems a reasonable man so that when [here it gets fuzzy as my brain is quickly deleting my memory] i grab both bags and drive my late '70s model black trans am [the type burt reynolds used in the film smokey & the bandit (1977)] to the ferry across the bay then to the train station i realize with horror that i grabbed the recycling rather than the stuff and now i don't know what to do when the lights turn on
