The strange feeling of becoming someone else
Yesterday, as the day unfolded, I kept asking myself the same question: why do I seem to become a different person throughout the day?
I woke up feeling deeply calm. Everything moved slowly and peacefully inside of me. The morning felt light, almost effortless. Then, without any apparent reason, I suddenly felt an intense wave of euphoria. Not the chaotic kind, but a pleasant emotional expansion, as if something inside me had opened and allowed more life to enter.
But as the afternoon slowly arrived, my internal world changed again. Thoughts I did not enjoy started appearing out of nowhere. The strange thing about these thoughts is that they usually come when everything seems fine externally. Nothing had happened. Nothing triggered them directly. Yet they appeared, almost like a completely different version of myself had suddenly taken over my human experience.
While I was cleaning the kitchen, I was listening to a podcast talking about thoughts and how they supposedly create reality. On that subject, I remain skeptical. I do not necessarily believe that thinking something magically manifests it into existence. However, I do understand that everything we eventually do begins first in the mind. Before every action, there is a thought. Before every change, there is an internal interpretation.
The mind is where every reality begins taking shape.
The neuroscience behind emotional shifts
As I reflected on all of this, something became very clear to me: maybe we underestimate how biologically dynamic the human experience actually is.
From a neuroscience perspective, we are not emotionally static beings throughout the day. Our internal chemistry changes constantly. Hormones fluctuate. Neurotransmitters rise and fall. Brain activity shifts depending on stress levels, sleep quality, blood sugar, sunlight exposure, overstimulation, memories, and even unconscious emotional associations.
In the morning, the brain is often more regulated by the prefrontal cortex, the area associated with rational thinking, emotional regulation, planning, and perspective. As the day progresses and mental fatigue accumulates, the limbic system — the more emotional and survival-oriented part of the brain — can become more dominant.
This is one reason why intrusive thoughts, emotional sensitivity, anxiety, or existential reflections tend to intensify during the evening for many people. The external world may not have changed at all, but the internal lens interpreting reality certainly has.
And perhaps that is why sometimes we genuinely feel like different people within the same day.
Because, neurologically speaking, different internal states are temporarily leading our perception of reality.
Thoughts are not fixed truths
Today, when I woke up, I had a realization that brought me a surprising amount of peace.
If my thoughts are constantly changing, then I cannot truly be my thoughts.
Some disappear within minutes. Others contradict each other. Some emerge from exhaustion. Others from fear. Some are simply old neural patterns replaying automatically because the brain has learned them through repetition.
But none of them remain permanent.
We often identify so strongly with whatever thought appears in our mind that we immediately assume it reflects who we are. Yet if identity changed every time a thought changed, we would become completely different people every hour.
That realization made me question how much unnecessary suffering comes from believing every mental narrative we experience.
Not every thought deserves emotional attachment.
Not every internal voice deserves authority.
And not everything that crosses the mind deserves to become action.
Meditation taught me something important
I am used to meditating, but yesterday I chose not to silence my mind immediately. Instead, I simply observed what was happening inside me.
And maybe that observation itself taught me something important.
There is a massive difference between experiencing a thought and becoming that thought.
Meditation has never made me emotionless. If anything, it has made me more aware of how temporary emotions and mental states truly are. The peaceful version of me is temporary. The euphoric version is temporary. The fearful version is temporary too.
They all move through consciousness like weather patterns moving through the sky.
The problem begins when we mistake temporary mental activity for permanent identity.
Shared human experiences
Perhaps this is one of the most shared human experiences, even if we rarely speak about it openly.
Most people carry multiple versions of themselves within the same day. The calm one. The hopeful one. The insecure one. The exhausted one. The inspired one. The one who dreams. The one who fears.
And maybe emotional maturity is not about eliminating any of them.
Maybe it is about learning not to fully identify with every passing mental state.
Because if thoughts are constantly changing, then perhaps the most real part of us is not the thought itself, but the awareness quietly observing all of them come and go.
