You only dream we live just so long then die

It’s a humorous take on the realization of mortality.

The premise is that, at some point, prehistoric humans had to have experienced the first conscious realization that life ends. The comic presents that as them having previously existed in a state of ignorance of death entirely to highlight the shock that whatever the first truly conscious being must have had when faced with the horror of knowing they would die some day, as opposed to just living without that dread.

It limns the ageless question of whether consciousness is a curse or a blessing, and might we be happier without it.
