Last night I dreamed I was shopping in a truck stop.

There was a display of homemade purses that I thought were very cute. When I ooo'd and ah'd over them, the shop owner (a darling older woman) remarked, "What I need is a Dune fan!"
I turned to my left and found a giant shelf of rental movies. and sure enough, she had nearly a dozen copies of Dune.

Moments later, a young couple walked in. The young lady described the kind of movie they were looking for, and the shop owner nodded in thought for a moment, then plucked a movie off the shelf.
"Here! You want to watch Dune!"
When the young woman frowned in doubt, I exclaimed, "It's Kyle MacLachlan! You'll love it!"

My outburst surprised everyone, including myself as I've never seen Dune (only parts of it as the husband clicks through the channels) and wondered how I even knew Mr. MacLachlan was in it.
And of course, the shop owner immediately eye-balled me as someone needing to borrow a copy from her.

Since I was now renting one movie, I continued to hunt through the shelf for more.
So engrossed in my search, I didn't realize I was groping in front of another fellow looking for movies. I apologized, moved over, and then recognized it was Willem Dafoe grinning at me.

Surpressing the urge to yell, "Hey! It's the Green Goblin!" I woke up.

Aside from me watching way too much TV, what do you think it all means?
