Billy Carson describes a meditation technique where you mentally travel to alternate dimensions to meet your future self living your desired life. He claims this lets you observe their choices and preview outcomes before making decisions in your actual timeline.

There's a multiverse meditation I do, a parallel meditation that I do. You can find your future self, the version of you that is doing and living exactly how you want to live and be. And you can actually use your mind outside of space and time and travel and traverse dimensions, traverse realities, to find and isolate that one version of you. You can observe, you can watch, you can even interact. And you can bring that knowledge back to yourself in this particular realm. You can also have a situation come up that you've got to make a decision and some action on. And you can actually pre-think your conscious thoughts, you can pre-think the actions you will take on those thoughts. And you can send your mind out of space and time to actually watch the unfoldment of what will pan out down the line, what future will wash over you if you take these actions or take these non-actions, or I change my energy into this, and I'm going to take this particular type of action, not this one, what's going to happen in the end result, you can see that timeline, you can witness and view that potential end result, giving yourself a much higher percentage of manifesting a reality that you want.
