For a similar kind of experience, but more down to earth, I would recommend the movies of Béla Tarr.
Anyways, there's a scene in the film with a pagan ritual that is shot with such dreamlike perfection. I remember seeing something from the corner of my eye and noticed there were three other film-obsessed laserdisc enthusiasts standing behind me mesmerized.
Andrei Rublev is on Criterion blu-ray now as a flawless restoration. Watching it recently, it's a bit heavy-handed, but still magnificent if you watch the film on it's own terms.
I think many of the visual techniques pioneered by Tarkovsky are now commonplace, but the meandering dreamlike pace and tone is still rare. Apichatpong Weerasethakul comes to mind as a director who can pull-off the dreamike stuff as well as Tarkovsky. See Uncle Boonmee Who can Recall his Past Lives (https://youtu.be/gqlD_VnsM-k).
