100%
I remember my journey began with lucid dreams.
I was a die-hard atheist at the time and I was 100% sure anything spiritual or energy related was either a scam or delusion.
But lucid dreams were āscience-approvedā so I practiced to learn and master them.
After some time I could memorize multiple dreams every night and I was aware Im in a dream in most of them, but I had little to no control over them so I couldnāt enjoy lucid dreams to the fullest.
Then, I saw some people on LD forums recommending various ways to ātrick your mindā into believing something.
Designing spellbooks, codewords, changing music on radio or channels on TV (In a dream) creating "dream-remotesāā magical wands, control pannels etc, and summoning them in every dream
It was all to make it easier for your mind to believe something is happening.
I wasnāt spawning pizzas with my mind, I was doing them because I used magical spells or dream-controllers, which was totally different thing
Well, not really, but to my mind it was, and thats all that matters.
It was easier to believe that magical spell or advanced device makes something happen, rather than me just āthinking something happenā
I improved my control over my dreams with those methods, and after some time I stumbled upon chaos magic.
You know, making sigils, doing rituals etc to convince my mind of something.
It looked silly at the first, but I tried it out anyway. I had some results with it as well.
Then I came across subliminals. Then energy work. Then Sapien Medicine
So I believe it is changebale, as I was a die-hard atheist and materialist.
But there needs to be a geninue desire to know know the truth.
And, as JAAJ said, you have to be open minded enough to recognize the truth when you see it.
In my case it was a clear step-by-step process:
Dreams feel very real while dreaming, yet controlling them with simple actions is possible.
So maybe there are means with which ārealityā can be molded as well?? (spoiler alert, there are )
The difference is, dreams are single-player while reality is multi player, so its not only one personās thoughts creating reality, but thoughts of everyone and everything, but thats another topic
