The mechanics are of value if you happen to be into science. Then you want to minimize misinformation, and it's nice if your reductionist side doesn't have to gravely doubt your explorer side's sanity, and curse all your habits and lament past choices. In tripping circles there's often a wish expressed for more "integration" to take place, and boiling all integration down to belief structure can result in feeling isolated from the world still. One has to wonder whether cults start this way.
I've had the most peculiar effects while tripping happen with birds, both on dissociatives and psychedelics. Cows notice these things as well, as despondent as they usually are. Even with arthropods there's more going on than is typically acknowledged. It really doesn't take that high level of neurological organization before at least some precursor mechanics of mind get booted up. If a fly lands on my face while tripping, it tends to land right in the middle of the forehead, where the pineal gland resides. This doesn't prove the insect brain transcends Newtonian mechanics as well, but it does suggest there's already a principle of virtual voidness at work, which seeks out resonance in similar ways as bees seek out flowers.
Edit: And Terence McKenna does suggest such mechanics could be mediated through pheromones, at least in his reported connection with butterflies. I don't think chemistry can explain distant birds singing in perfect sync and harmony with music on headphones though. This implies connection through the electromagnetic senses at least, if not through the principle of sheer physical non-locality.
