Falling into a dark abyss is normally the stuff of nightmares -- but for one unlucky museum patron, it was a kind of reality after he tumbled into an art installation.

According to the Art Newspaper, a visitor to a Portugal museum fell into an art installation that features a deep hole painted dark enough to look like a circle painted on the floor. The hole is part of the Anish Kapoor exhibition at the Serralves museum in Porto.

The installation that included the eight-foot-deep hole, aptly called "Descent into Limbo (1992)," creates the illusion of a endless void -- a disturbing concept if I do say so myself.

The hole is painted with an extremely black paint that helped create the illusion that the hole was bottomless, or lacking any depth at all. According to the Times, Kapoor purchased the rights to "Vantablack" paint in 2016, which absorbs 99.6 percent of the light that hits it.

Per the Art Newspaper, though there were reportedly many warnings to prevent a person from falling into the hole — and a waiver to inform museum patrons of the potential dangers involved in visiting the exhibit — the visitor seemingly didn't notice them and fell in anyway. Ouch. The exhibit's since been closed, but it's supposed to reopen in a few days.

The unlucky visitor suffered back injuries from the fall but has since been sent home, per the Times.

I feel like the big takeaway from all of this is that maybe it's not the best idea to step directly onto someone's art, orleave an eight-foot-deep hole in the ground unattended. But that's just one woman's opinion.
