Yes I have experienced it, no I don't at all believe that a drug enables our bodies to physically detect more than we normally can, I think that our brains just have certain ways to let us distinguish different sensory qualities and drugs can intensify or even extend these sensations.
With LSD I have more than once experienced a certain golden energy kind of light that was just beyond colors, like seeing matter completely indifferent of the wavelengths of light that they emit or absorb. It's similar to what I've heard 2C-E can do, i.e. mix senses into one synaesthetic supersense that uses indifferentiated experiential data. Synaesthesia has much to do with this kind of effect, I strongly believe.
