We wonder, when do we start doubting? We doubt since we perceive. And we perceive since we think; we think since we know, we know since we remember and modulate what is perceived.
Visual, auditory, tactile, gustatory, and olfactory stimuli are transformed into chemical compounds, into molecules that occupy tiny spaces, organized according to their order of arrival and with bonds proportional to the intensity with which they are perceived. These spaces, sometimes erroneously called frames, highlight the visual in images, without considering them as points and pixels.
Components such as emitters, receptors, membrane potential, fibrils, fascicles, nerve endings, synapses, cisterns, cerebrospinal fluid, cortex, gray matter, and glia serve as support structures for what we perceive.
Three-dimensional molecules couple to receptors that consume metabolically usable energy. This energy is not lost through entropy and helps maintain a molecular order that, according to its bonds, can be interpreted in superficial and deep terms. In less technical language, we could associate feeling with feeling and knowledge, suffering with suffering and knowledge, regret with regretting and knowledge, and so on with other terms like treatment, falling in love, enrichment, impoverishment, among others.
In a simpler but no less complex way, if after a period of inactivity we engage in an unusual activity, such as walking or watching an impressive TV series, that night we are likely to dream a vivid and clear dream, capable of solving dilemmas that we can't resolve while awake. Some of us wake up happy for discovering the simplicity of what was dreamed, but upon opening our eyes and facing reality, those memories fade away, leaving us without simple answers and longing for having perceived them with such clarity. Some attribute this forgetting to superficial distractions, while others relate it to the different stages of sleep. Possibly, it's a combination of both factors.
Personally, I have dreamed a lot and lived my dreams as if they were very real. I have felt fear and sometimes knew I was dreaming and tried to modify the dream in my favor. Now I try to write down what I dream to remember those moments of simplifying the complex, avoiding using my cellphone so as not to distract myself.
If this is true, then I understand why it is convenient to avoid distractions and focus. Exercising the mind with greater intensity will allow me to connect with my deeper thoughts, simplify the complicated, and surpass my own version every time I make a comparison.
So, we ask ourselves, since when do we exist and what is the magnitude of our doubts?
