Not just differences in brain chemistry, but differences in the complexity of their issues, differences in the number of occurrences of events related to their issues, differences in energy sensitivity, etc.
I don’t know that listening “more”–in terms of the number of times in a row–is the only answer. Some people might need to listen to it “more”–in terms of more frequently throughout their day or in terms of listening to it consistently over a longer period, as this field peels off layer after layer after layer, like an onion.
The 2x max protocol is because this field includes the SGB, which is a potent nerve block. Now, because it’s an energetic block (rather than the physical, medical one) it’s not going to operate exactly in the same way as the physical, medical one, but a lot of us want a functioning conduit between our bodies and our brains (look at the interest in brain enhancement fields on this forum). Since Dream doesn’t know each one of our needs, desires and medical functionality individually, it’s safest to err on the conservative side due to the SGB. Plus we don’t know the long-term effects of overusing (cuz none of ever spam these fields, right?
) even the energetic SGB block on our bodies.
So, for these reasons (and probably more), that guideline was spelled out in the description.
Anywho, I personally don’t usually feel fields. And for me, I find that my results are more of an unfolding over time, especially with something like New Perspectives, which shifts my perspectives little by little by little until I can notice that they’re in a different place than where they had once been. Is that because of the passage of time or because of this field, I can’t tell you for sure. But I give myself points for being an active contributor to my shift (thanks to my consistent listening to my fields) without al the expense and angst of Therapy or “shadow work.”
And if you’re using a bunch of fields, tags, etc. all at once, your changes (and what’s giving you those changes) will be harder for you to discern. I know this, too, from my own experiences.
