True but Trek has traditionally shied away from religious notions and it becomes hard to deal with non-scientific notions of an independent consciousness or soul without straying into that territory. Studies on alzheimers are beginning to yield pretty strong information on how memories are stored and accessed physically. Having said that, Trek has plenty of examples of 'energy beings' who could not exist in our dimension based on our current understanding of physics. But the two notions come into conflict. If our memories are physical then what does that even leave for an independent consciousness? A multidimensional existence seems to me to be the only sensible explanation that covers both bases i.e. our quantum information exists in another dimension as well as our own and transporting simply phases or breaks down the physical copy from this dimension while leaving the 'soul' in the other dimension intact and linked on a quantum level to the energy in the matter stream in our dimension.
