The night before last, I dreamed that I was reading a notice written up on a door, and I thought 'How interesting - I can read every word without difficulty' although I then realised that the words in fact taken together made no coherent sense. (I can't remember any of them, unfortunately; I lazily went back to sleep after waking from this dream.) The odd thing is that for my thought to make sense, I should have been aware that I was dreaming (because if in a 'normal' dream you think you are awake, you should not be surprised that you can read), and yet I had no such explicit awareness. It was totally unlike my usual lucid dreams, which begin with a sudden realisation 'this is a dream'. So what is going on here? Is this a sort of low-level, sub-lucidity phenomenon? Any views?
