I don't hear things, but when I'm going low I do find my hearing starts to dull. I also find I get slight colours flashing and get a metalic taste in my mouth.
I guess if I go much lower than the above and my glucose starved brain extrapolates the dodgy data it is being fed, then I guess that I could start to believe that I've licked a very colourful metallic robot whilst it sticks its fingers in my ears.
I'm looking forward to that one
