"Can we ever know if what we’re experiencing is actually real?"

This is a profound philosophical question that has been debated for centuries. It touches on various fields such as philosophy, cognitive science, and even physics.

1. Philosophical Perspective (Solipsism): Solipsism is the philosophical idea that only one’s own mind is sure to exist. For example, you might be dreaming or in a simulation and everything you experience could be an illusion. In this view, it’s impossible to know if what we’re experiencing is actually real.

2. Scientific Perspective (Cognitive Science): Our brains interpret the data received from our senses to create our perception of reality. However, this interpretation can sometimes be flawed, leading to optical illusions or hallucinations. For instance, when you see a mirage in the desert, your brain is interpreting the light refractions as water, which isn’t actually there.

3. Physics Perspective (Simulation Theory): Some physicists and philosophers have proposed the simulation theory, suggesting that we might be living in a sophisticated computer simulation. If this were true, our experiences would be “real” to us but not “real” in the sense of existing in a physical universe.

4. Pragmatic Perspective: On a practical level, most people operate under the assumption that their experiences are real because it’s functionally helpful. For example, if you feel the heat from a fire, it’s safe to assume that the fire is real to prevent harm.

In conclusion, while we can question the nature of reality, we often have to assume our experiences are real to navigate the world effectively. However, it’s important to remain aware that our perceptions can sometimes deceive us. This awareness can help us question our assumptions and keep an open mind.
