I was fiddling with my phone and decided to see what kind of info they ask for when you sign up (I've never done it) and someone thought I was taking a picture and yelled at me to stop. I explained that I wasn't, and when I looked down, I'd somehow accidentally completed the registration and an app was already loaded and running. I freaked out and tried to hit the "home" button on my phone, but the app was evil and none of the buttons did what they were supposed to. It had taken over my phone and there was nothing I could do about it. I was trying to figure out how to close the account before anyone noticed I had joined, and I woke up.
I was so glad it was just a dream.
