Same. As soon as I really let myself consider how vast, empty, desolate empty space is and then imagine myself floating in it with no reference and unable to tell if I am up or down or going anywhere ... I get all sorts of dread.

That being said... I'd love to if I were terminally ill yet capable enough to understand what was happening -- to be yeeted into a super super massive blackhole that was not feeding such that I would not be torn to shreds or vaporized by the accretion disk and ultimately understand what lies at the center of my now time horizon...
