To paraphrase the late, great Mitch Hedberg:
My darling Marcie thinks the Levitra guy is HOT! I think she prays for Levitra Dreams.
I’ve never had commercials in my dreams but I have had “Intermissions” complete with the words “Now back to the movie”. I’ve also had subtitled dreams.
A couple of nights ago I actually dreamed I was posting on the SDMB and playing Kingdom of Loathing. How exciting. I think I need to get out more. 
I frequently have dreams about video games. Sometimes, if I’m heavily into 2 games at the same time, my dreams combine them together. Once I was in a sort of Diablo RTS world, with massive armies swarming and dying around various of the demons. On the other hand, if I’m into a text-only game I’ll have text-only dreams, which is somewhat disconcerting when I wake up, as I briefly expect the real world to be text-only:
You are lying in bed. When you open your eyes you find yourself staring at the ceiling, watching a spider grow larger as it descends towards you on a thread.

Oh man, I love dreaming about video games. I’ll play for an hour or two, then go right to bed and dream about it all night long. Multitasking!

I used to do that in college with open-book, unlimited-time math exams. Work on the test all evening, go to sleep with the test papers and book by my pillow, dream about the test problems all night, wake up in the morning, reach for the papers, and get back to work on the test.
I like math (enough to major in it in college, in fact), but those experiences were not a barrel of laughs.
I have only recently been remembering my dreams. I never used to before, but in the last 6 months or so, I have.
And they are all lame. Boring, completely devoid of entertainment, tension, eroticism, or humor.
Last night, I dreamed about making some flan from the mix we have in the cupboard, but discovering we didn’t have enough milk. That’s it.
Pathetic. A Levitra commercial would be a major step up.
I’d like to add that I think I’ve had sex with every conceivable thing in my dream. You mention it and I’ve had sex with it. Even a cat. Yes a common housecat. I don’t really understand the logistics of it either. But I did. The cat was asking for it though.
