Both deal with a supernatural theme. muis although no similarity in the story, two animes are considered 'slow' by several people, you have to always be attentive to detail.

Investigations of the human psyche. Deal with the overlap between the world of the human, and the world of the supernormal, and the creatures within it. Have a quiet, yet pensive tone, with occasional horror, and take place in the countryside. Feel a little unusual, even experimental. Similar music. Mushi-shi is episodic, while Ghost Hound follows the same set of characters throughout.

Same mystery/fantasy theme while being totally completely different.
Lots of small details making them both slower animes

Both are slow-paced series with a very similar animation style which do a very good job of mixing science, natural phenomenon, and spirituality.
