How to live in two worlds at the same time

There are some people that live in two different worlds at the same time. I have always wondered how that can be possible. The other day I caught one of these "two-worlders" when they were trying to do it and I asked them if anybody could do that, anytime they wanted, wherever they wanted. They told me anybody could. They told me all they have to do is try. They told me it helps if they are a bit fucked up in the head-that helps a lot, according to the "two-worlders". I found them funny.

But I believed them. And now I am a "two-worlder", too.
