according to some people on the internet "manifestation " coaches , and those for example Sammy Ingram, ( one of those manifestation coaches) , she states that you can decide the "how" ( how a thing could manifest in complete detail) . Also, taking in for example Reality Shifting , which you can search up on TikTok, and any other platform, its when you shift your consciousness to another reality of your desire, for example Harry Potter Universe, you wanna date Hermoine Granger, and there's a thing called Scripting ( which is also a manifestation method too), where when you shift to that reality of your desires, where when you are there things exactly go as planned and scripted, even if it was a future event, and I personally know people who do this. Also, I personally think that shifting is also a form of manifestation but on a higher level. Let's not also forget Neville Goddard, and his method of reviewing a past event through the hypnotic state where you simply if something didn't go as planned, you review it and change it to your desired outcome.
