I distinctly remember being 6 or 7 drifting to sleep one night and suddenly visualising what it would be like if there existed nothing at all, not even empty space but nothing, no Universe and nothing ever happening ever or anywhere. It was terrifying.

It was about the same time that a family member had died so I was coming to terms with the fear of dying for the first time, so I guess that's what triggered this.
