Today in the morning I was commuting to work by train as usual and had quite unusal experience. I was napping as always and just before the train terminated I fell into a strange dream-like state. My visual field was bright but quite featurless, except some geometric patterns that resembled rainbowy circular diffraction patterns dancing about. I was perfectly aware that I am sleeping and I was eagerly awaited onset of a dream. I even tried to conjure something, but after some 20 seconds of this state I heard outside sounds and woke up. This experience was quite like the “interplay” I sometimes have between ND and LD.
