That is little bit speculative. That something is sentient doesnt have to mean that it must be Soul Stone. Who knows, maybe all Infinite Stones are sentient, maybe it is a thing of Aether only. It is my speculation, which I show only as an example that I dont expand myself. The Soul Aether does not sound to fit, because beside the sentience I dont see anything that matches what Aether displayed, or was said to be able to do.

The "reality" can be seen as "material world", which can be changed by Aether into "darkness", which can be the dark matter or something. The "Reality Stone" sounds far mroe plausible than "Soul Stone", because it greatly affected the thigns that were happenign around itself. But I dont know how Soul is made up in the comics, so cant dismiss it completely.
