No. Because it's not real. Trust me, I wish it was. But it's not. There is no respected scientist that has said it is. The CIA documents were completely misinterpreted - they also didn't give any "proof." And some of the steps to visit another universe are pretty similar to that of lucid dreaming. Also, the fact that that if you die in your desired reality, you'll wake up here, proves it's just lucid dreaming. There is no actual evidence and many of these reality shifting stories sound as if they just came from some stupid fanfiction. And, if shifting was as real as all these people claim it to be, wouldn't have science found out about it first - not some teenage girls on Tiktok? Imagine the advantages of it. What if someone decided to shift to a reality where the cure for cancer was already made. They'd simply have to recreate it here. But they can't because in a dream, you can't.
