Yes, you tell her

"I had a weird dream last night," you begin.

"The wet kind?" asks Miranda with a grin.

You shake your head. "I dreamed I spoke to the devil, he told me he was giving me absolute power over everyone and everything, and when I woke up, it was true."

"What do you mean?"

"I mean I have absolute power," you insist. "I can do anything. Anything I imagine just happens."

Miranda looks dubious. "You're scaring me a little. What's it called, delusions of grandeur?"

You silently wish that she'll be aware of any changes you make, and then try to come up with something.

"I've got it," you say. "I went to Macy's and did some mattress shopping."

"How many did you test out?" Miranda's back to grinning. "No wonder you've got delusions of grandeur -- those girls are on their backs in 5 seconds, and it's great if you can stand the sales talk. I hate to tell you this, but they hate guys who try and then don't buy, even if the guys are good fucks."

"No, I bought one," you say. "Problem is, it's a king size."

Miranda indicates the full-size bed she's sitting on. "You better call 'em and cancel, 'cause that's not gonna fit in here. A king's, what, three times bigger than this? And since when do you have enough money to buy a mattress?"

You ignore the question for now; instead, you stand up, put your hand to your chin, and look thoughtfully at your bed. "If it won't fit, then I'll just have to make it fit." You look straight at Miranda and say, "I wish my bedroom was bigger, including a king-size bed."

"Holy shit!" screams Miranda as the bed she's sitting on enlarges. You stand as stoically as you can manage as the walls move and your furniture shifts position.

You sit down next to her as she looks around, amazed. "That's just -- I mean -- holy shit. No, I said that already. This'll make us more comfortable, I guess. But what about -- you didn't have all this stuff before."

"What?"

"Like that." She's pointing at the corner where two leather couches face a huge TV that appears to have a couple of video game systems hooked up to it. "All you wished for was bigger, with a king-size bed, but now you've got more stuff."

You point to your head. "The wishes get shaped a little by what I'm thinking, not just exactly what I say. I guess I was thinking about a more luxurious room, too, one that would be part of a bigger house."

"Well, you've got everything in here but a stripper pole!" Miranda exclaims. You, of course, point to a spot near your bed where a vertical brass pole appears, attached to the floor and the ceiling. She gives your shoulder a playful shove. "You're crazy!"

"So do you want to make a wish?" you ask.

Miranda gasps. "Really?"

"Of course!" you exclaim. "What, you thought I was gonna keep this power all to myself? Try me."
