All you can do is altering time's perception. Remember that you are still asleep, and you'll wake up at some point. But altering that perception? You do it every time you're awake. When you're having fun, the time seems to fly, and when you're bored, the time seems to slow. When you're in panic, the time seems to stop. And so on and so fourth. There's even studies going on regarding top athletes that experience time slowing down experiences.

There's actually some range of "abilities" that are still left to be explored, even in a scientific point of view. Things like synesthesia, time dilation, dream characters, etc etc. I would use BrandonBoss's direction and ask one of our most experienced lucid dreamers about their experiences, and hopefully try to make some sense of it. I don't think that anyone has come with a solid way to perform it though, but it's for sure worth a try ^^
