So yeah this is a complicated subject. I studied psychology and work in psychiatry so I'm well aware that a large % of abnormal experiences people have are just in their brain, and that human senses and memory are easily deceived. However I do think it's not very helpful to dismiss outright any weird or seemingly supernatural experiences people have. Consider that before the internet helped spread awareness of conditions like sleep paralysis, tons of people were still having those experiences, without being able to easily find an explanation for them. You could imagine a person living their entire lifetime in fear of what could happen at night, and not being able to talk about it for fear of ridicule. You want to keep at least some avenues open for people to talk about abnormal experiences without immediate judgement.
There is also an aspect of skepticism that I dislike which is what I call the "weather balloon syndrome" where someone will detail an experience, only to be met with an explanation that doesn't really cover the experience completely. I.E. "i saw a huge craft with multiple rows of lights spinning and then it suddenly zipped off into the sky" can't be explained by "weather balloon" or "swamp gas", and it's kind of insulting or dismissive to try. At least give people the benefit of the doubt that they are somewhat accurately recounting what they saw. If it was you, you would also at least like to be taken seriously.
