Quantum mechanics is the world at a microscopic scale.

How does the quantum description of reality, which includes elements such as the superposition of states and wavefunction collapse or quantum decoherence, give rise to the reality we perceive?
Your reality is only what you perceive it to be. Perception is reality, by definition. We believe what we perceive to be accurate, and we create ourrealities based on those perceptions. Fact is what you choose it to be.

Quantum mechanics suggests that we perceive at most a tiny sliver of reality. We knew that the visible spectrum is only a tiny part of the spectrum of electromagnetic radiation. What you see, hear, and touch is only part of what is going on around you.
How well our perception matches that of reality is often referred to as situational awareness.
Quantum decoherence in physics gives rise to the reality we perceive in the process by which a system’s behavior changes from that which quantum mechanics can explain to that which classical mechanics can explain. Quantum mechanics is a description of the world at a microscopic scale.
Quantum superposition is a fundamental principle of quantum mechanics. It states that, much like waves in classical physics, any two (or more) quantum states can be added together (“superposed”), and the result will be another valid quantum state. It has been proven that quantum states exist in superposition. Conversely, every quantum state can be represented as a sum of two or more other distinct states. . The principle of quantum superposition states that if a physical system may be in one of many configurations, arrangements of particles or fields, then the most general state is a combination of all of these possibilities, where the amount in each configuration is specified by a complex number. Superposition, however, is just a mathematical idea at this time.
Wavefunction collapse: In quantum mechanics, wave function collapse occurs when a wave function, initially in a superposition of several eigenstates, reduces to a single eigenstate due to interaction with the external world. … Significantly, the combined wave function of the system and environment continues to obey the Schrödinger equation. This wave function always collapses instantaneously upon the measurement of one partner.
