Yeah, so Hidamari isn't for you right now. Not surreal in the least.
When the DVDs are finished, you may want to check out ef ~a tale of memories~. SHAFT is good for graphic design. (But again, not all that surreal.)
Princess Tutu stands out as firmly post-narrative, but that's with respect to the plot, rather than the animation -- and it takes a while to get there. Fails your criteria by being 26 episodes, and not many of them all that surreal.
