Well, you know, experience, unless we do proper experiments, isn't so reliable way to acquire knowledge. It's true that the reality is essentially just a name we give to the world our senses give us access to. However, we experience all sorts of illusions, cognitive biases, and even hallucinations. Scientific method compensates for all of them. So, why not trust science over your own experience?
Only trust science in matters of empiricism. Trust your experience when exploring the creative, the spiritual and the sublime.
I don't think that spiritual experience is a way of knowing. Maybe it would be if millions of people talked with god and got consistent answers, but that's not at all how it works in reality. Also, think of this way: if you saw a dragon, would you think it's really there, or would you think that you are dreaming or hallucinating? Our culture makes us think that god or spirits are somehow different, when, in reality, they aren't. You can call me close-minded because of that, but, let's face it, if you, for example, reject evolution or anthropogenic climate change because of your religion, you are also close-minded.
As for exploring the creative, I am not so sure. You can safely reject what others tell you if they just tell you advices of the people who just happened to be successful by luck. But if someone makes a scientific study about, for example, how to program more productively, and comes with statistically significant results, I will take that seriously.
