When you get sucked into reels, you go from "here" to "there," and in the process, while you are "there," your entire whole self is destroyed. The same psychological phenomena happens to gambling addicts, alcoholics, or users of heroin. It has fewer physiological downsides and side-effects as those things; the only material loss you have is the loss of time.
But far more remarkable than that it's simply a waste of time, and rarely articulated, is this psychological loss. The destruction of the self. That echoes through a person's life, to their relationships, their self-construction, etc. It is those echoes that we are now dealing with on a mass sociological scale.
By the way. "There" has a lot of upsides too. People can be creative, productive, expressive while they are "there" too. Creating, being funny, being social, etc. That's why this is so hard.
I'd like to say I'm astounded when I hear other people visit other worlds when they read, but really that whole idea is so foreign to me, it might as well be a complete lie. I have no thread in which to pull on to begin to imagine it. I chalk it up to aphantasia, but my point is that not everyone processes and interacts with the world in the same way you might.
Does your mind conjure no images while reading this?
I'm not the person you're replying to but the answer, for me, depends on what you really mean by conjuring images. Very technically no, I see no images for this but I don't know if that is truly the whole point of what you're asking.
I mostly understand what is happening but I also really struggle to get the angles right in my mind of someone swinging a mallet quickly and one time hitting a shin and the next aimed for the head so maybe I'm missing something.
There are other senses involved as well even though it isn't visual, including things like spatial reasoning or maybe even something like proprioception - like I said it's hard to explain.
I can imagine myself in this position better than I can "visualize" it happening to someone else.
Interestingly enough, I have very lucid dreams and have realized that I am able to visualize (with color!) inside of them. I can't imagine being able to do that at will while awake, must be amazing.
