The section above seems to explain why this article is written the way it is. Many people do experience sensations or see things that we otherwise cannot. They may have heightened sensitivity or could have a mental or neurological condition that produces these experiences. Some people may feel like they are going crazy seeing or hearing things that aren't actually there. Others feed into the experiences and believe they exist, like targeted individuals do. Someone that may be unsure if they are really seeing lasers or feeling indeterminate heating may and hasn't totally fallen down the DEW or TI rabbit hole could benefit from seeing something that basically says "I believe you're hearing/seeing/feeling these things, there may be medical explanation so you may want to see a doctor."
