Although RYT is based on science, I still think there's a bit of "magic" or science that's too absurd to be considered proper science. I mean, what are the chances of a canine-human species existing? Or worse, how do you explain Tucker's abnormal comprehension abilities? Even if the hallucinations are side effects of Mæron or just stress, I doubt any of them would give you the ability to understand the Carain language. The only explanations I can think of are time travel or parallel dimensions. I simply can't swallow that Tucker was simply transported to another place in the universe where a species so familiar to humans exists, not only in appearance but also in behavior and culture.
