Never had TikTok, so not aware of any trends, but still got something to say. I've been studying realities and the more I did, the less sense it made...anyway:
Xianity uses this trick to manifest the reality based on the content inside one's head. Virtual reality so to speak. Or delusions. Most of them are collective, aka hive mind.
When you don't have spiritual power and knowledge the only thing you can do is to adjust those delusions. If you want to manifest them, you need power. With hive mind some things can manifest and this what enemy exploits.
Shifting realities are possible tho.
I was too lazy to fix some things, so that was one of the reasons I've started to mess with them, but my advice: don't.
There are infinite number of those realities and your soul exist in all of them at the same time. Everytime you turned left or right or make a choice reality splits and any minor action can lead to big changes.
Good indicator that you shifted successfully is a traveling dream. Like flying in airplane or having a trip in a train.
You can easily move your consciousness between simular realities, and sometimes this trick is used by your guardians to save your ass from trouble. If you had near death experience and you were sure that you gonna die and for some reason you made it, that's how it happens. There are realities where we are dead already, the trick is not to be present there when it happens.
Big changes requires time to manifest and your mind is a limiter here. You should learn to let it all go, like literally everything, close to amnesia if you want big changes.
There are matrix glitches when you do that.
Like for all sudden your friend can just stop talking to you or other people you haven't talk in years appear and in a short time you talk almost everyday. In some cases people may die after those shifts. And from that point you can't go back to where this person is still alive. At least I wasn't able to.
Sometimes some entire buildings can be gone or you may see a different store at the same spot. If you start asking people, they will tell you it was always like that. It also feels differently.
This all looks like fun , but at some point you start question reality. You don't known what's real and what's not and in worst cases you can go insane. You may also stuck somewhere in between and people won't notice you ,like you are a ghost. Also there are some kind of beings that are guardians of those realities. They are not enemy, but they are not from Satan either. If you cause too much trouble, you may get their attention and you don't want that.
