Had a dream about yokai in ghost of Tsushima

I had a dream last night that is was playing Ghost of Tsushima. I was walking up this mountain to a shrine and I saw a dog climbing up it as well. I followed the dog to the shrine but when I reached it I didn’t see the dog anywhere. But what I found at the shrine was a kamaitachi, the sickle weasel yokai. The game showed I could equip them as a cosmetic or a weapon. The dream ended there but it got me wondering what Ghost of Tsushima would be like if it had more creatures from Japanese mythology in it. (Besides the Oni.)
