You have an existential crisis

Your mind races as you think of all of the possibilities the newfound power has opened up for you. All of existence rumbles as it tries to keep up with your thoughts.

"Wait, wait, wait, stop!" you say as you become cognizant of the inherent danger of having absolutely any of your un-moderated thoughts become reality. The rumbling stops, and you peek out through the blinds of your window to see that all of existence has indeed stopped. In the early morning light, you can see birds frozen in mid-flight, and a jogger caught mid-run. She's pretty cute, you wonder -- NO! That sort of thing is what caused a random celebrity to pop into existence in your house to begin with! Obviously, you need to place some restrictions on your own powers before you give your universe galactic cancer.

First, in case you really fuck up in such a way that you don't know how to fix it, you need to be able to return to a previous point in time. Preferably here, where time is frozen. Like a save system in a video game, you think it and it happens. A UI screen pops up in front of you, like the save screen of several of your favorite RPG's mashed together. You touch the top one, and it saves, just like a video game. You will a message to appear on your wall, "TEST," it says, and then you load up your previous save. Instantly, the message is no longer on your wall. You lock the save so that you can't overwrite the slot.

Closing the Save UI, you ponder what to do about your powers. You don't want to completely get rid of being able to think things into existence, in case you're in a situation where you cannot speak, but having just ANY of you thoughts become reality is a frightening prospect to ponder. The room becomes darker and gloomier, as though reacting to your emotions. Yeah, that needs to change. Then the perfect fix occurs to you: intent. You make it so that the only way you can make changes to the world is if you mean it. No more accidentally zapping a celebrity to your home to have her suck you off. From here on out, the only way you're having a celebrity suck you off is if you wanted it to happen, not because of some idle fantasy.

Without actually seeing anything change, you know that the changes to your powers took hold.

You decide to test it out. You open your blinds, and look at the jogger across the street, looking at her fit form and daydream about seeing her form without those pesky clothes in the way. The image forms in your mind, but the jogger remains clothed. Okay, it's working so far.

Now you really think about her being naked, her shorts and sports bra vanishing into nothingness, wanting it to happen, and it does so instantly. You can see her tits and ass hanging out for all to see. You will them back, and they're back exactly how they were. Which is good, because you didn't even think to remember what color shorts she was wearing. It appears that existence did the remembering for you. That's both convenient and good to know.

You close your blinds and will time to continue moving. The rumbling from before you stopped time starts back up, and then quickly fades. You weren't paying attention, but when you stopped all of existence, the resulting silence had been deafening. Well, you were focused on more important matters at the time. Heh, "time".
