The Language of Dreams and Visions

Have you ever wondered why dreams are symbolic - why can't they just tell us 'straight'? I considered this question, allowing it to rest lightly in consciousness, until it finally struck me - words are just abstract symbols for the objects they signify. We must first learn the language in order to be able to read and therefore to understand, but this language of words belongs strictly to the quotidian level of consciousness that we are so accustomed to occupying. So, let us postulate that dreams/visions are some kind of content-rich symbols for a language of a higher consciousness.

Another consideration following from this concerns the inability of ordinary spoken/written language to adequately convey the experience of dreams and visions. Examination of the previous argument suggests an answer via a simple metaphor: how well does a (3-dimensional) model of a tesseract (a 4-dimensional cube or hypercube) convey its essence? The answer is obviously not very! We can easily interpret a reduction from three to two dimensions, but that's because we occupy three. We would need to be able to occupy a fourth spatial dimension to fully comprehend its nature, therefore we need to raise consciousness to the next level in order to be able to properly and (theoretically) unambiguously comprehend the content of that higher language.

But how to do it? Anyone know of a reliable source of DMT? ;-)
