The problem here is that science isn't the only paradigm or even the most relevant paradigm with which to interpret these experiences. That is not to say that scientific method cannot be applied, but there is little in the way of frameworks and tools for exploring altered states of consciousness and subjective experience. There isn't anything even close to a consensus on the nature of consciousness or whether it even exists, let alone the specific phenomena experienced subjectively by consciousness, so trying to cram them into inadequate scientific models will not bring about much insight. This is all addition to the fact that science has really only tackled the capture of knowledge about the objective world, that being the shared world between humans, but is not the best tool for approaching the subjective individual experience. Philosophy and metaphysics are better suited to this, as science says nothing about the "reality" of something.
