The fact that death will also turn out to be not perfect, just like life, or will turn out to be not universally the same pleasantly for everyone who comes to it.
I have ADHD and a fear of the dark. The only thing that can come to our mind that remotely resembles death is constant emptiness and silence, and for me, as someone who literally addicted on constant stimuli for my perception, as a person who has YouTube with videos and music open on other monitors and 50 browser tabs "for later", it definitely scares me.
If I had to spend an infinite number of minutes in a pure black void like this
, it would be really relieving for a while, but sometime after over9.999787e+12 years, it would become painful for me to have thoughts without having any meaning for them, and it would be more like durance than release.
We very often throw around such concepts as "eternity" "infinity", but usually we mean something very very large, but still finite, and we have a very poor idea of what it means when something is TRULY ETERNAL because it can literally mindf*cks. You could continue to think about it, but I wouldn't advise it
The only consolation for me can be that, as Schopenhauer said about death as "the temporary end of a temporary phenomenon". Confirmation of this can be considered the fact that we suddenly already have an example when death was over - when we were born.
