We assume our awareness is fixed, but our brains are flexible. Discover how neurobiology shifts your perception and how to navigate these states.
Normal consciousness is essentially a very controlled, very efficient hallucination that matches reality well enough to keep us alive; it’s a user interface for reality.
Exploring the boundaries of states of human consciousness.
According to the script, the brain is not a passive observer of reality but an active "prediction machine" that generates models of what it expects to find in the world. Instead of simply recording sensory data like a camera, the brain uses high-level beliefs, or "priors," to filter out noise and maintain a stable "baseline" consciousness. This process is designed for efficiency and survival, essentially creating a controlled "user interface" for reality that minimizes prediction errors.
Altered states are explained through the REBUS hypothesis, which stands for "relaxed beliefs under psychedelics." In these states, the top-down "guardrails" or high-level predictions of the brain relax, allowing bottom-up sensory information to flow more freely and "anarchically." This leads to increased "entropy" or complexity in brain activity, enabling parts of the brain that don't usually communicate to engage in "cross-talk," which can result in experiences like synesthesia or a dissolved sense of self.
The thalamus acts as a "switchboard" or "conductor" that orchestrates the state of the brain by managing the integration of information across different regions. It decides which sensory data reaches the cortex and ensures that various parts of the brain play "in sync." When this thalamocortical connectivity is disrupted—such as during deep anesthesia or in disorders of consciousness—the "stitching together" of our unified experience fails, and the complexity of our mental state drops.
While both states involve the "default mode network" (the brain's inner critic) going offline, they represent different paths to the boundaries of consciousness. Flow is described as "extreme alignment" or "transient hypofrontality," where the brain operates with maximum efficiency and a laser-like focus on a task. In contrast, the psychedelic state is "anarchic," acting more like a "floodlight" that destabilizes patterns to allow for new, flexible connections. Flow is a state of optimal arousal where challenge meets skill, whereas the psychedelic state is a more raw, unfiltered experience of sensory data.
"Set and setting" are crucial because when the brain's high-level "priors" are relaxed, the individual becomes extremely sensitive to internal and external signals. Because the brain is in a "pivotal mental state" and looking for a new model to adopt, the environment and the person's intention directly shape the outcome of the experience. A supportive setting can guide the brain toward healing and pro-social "oneness," while a chaotic setting can lead to dread or the "locking in" of maladaptive mental models.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!
@ladyInfinity
I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.
@jayallen
The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.
@Raguipa
What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.
@colonyofcreatorsNGO
I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.
@BeFreed user
It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.
@austinakon
I love this app. Used it for several days and I cannot stop listening. Such a great way to start.
@jcrules328
I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.
@DanielCZ
I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.
@BeFreed user
I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.
@Brad
I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!
@BeFreed user
The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.
@jayallen
BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.
@BeFreed user
At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!
@matteo77
BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
