Hello, dense phobia is a common phobia, people who see dense things are prone to project the sense of denseness onto their own bodies, resulting in unpleasant or even nauseating feelings. A single adverse reaction draws attention to the feeling, the attention focuses on the feeling, and this focus reinforces the feeling. So there is a clear feeling of nausea, but you can't help but look at it. Attention has been drawn to it, and if you don't want to look at it that's attention fighting it, and if a person is fighting it internally, then the feeling of being uncomfortable and twisted arises. Suggestion is to look at it, look at the end to do what you want to do, transfer the attention to your work, over time the attention to forget that feeling. Don't force yourself not to look, every time you force yourself is to remind the attention once that dense thing is disgusting.
