Explosive decompression won't happen in space, under normal circumstances. It is a thing that can happen, but it requires a drop larger than 1atm -> 0atm to overcome the strength of human skin. People have literally exploded from a pressure drop, but they were deep-sea divers in a decompression chamber that lost integrity and went from 9atm -> 1atm[1], a drop 8x larger than going from sea-level atmospheric pressure to vacuum.

From the article, it sounds like some of the symptons resemble "the bends" divers have when they surface too quickly. The cause of the bends is the change in pressure no longer being sufficient to keep the nitrogen dissolved in your blood, dissolved in your blood. Bubbles in blood veins are bad news.

Pretty much all of the issues with vacuum have to do with liquids becoming gases, and unsealed gases wanting to disperse. I have to imagine it's goddamn weird feeling the water evaporate off your eyeballs.
