Last night, I had a dream. I found myself being interviewed by various professors. One of them told me it was vital that I understand and present a proof of Schur's lemma. I did not remember what Schur's lemma was until I awoke, anxious, and looked it up.
Why do I never (remember) dream(s) of relaxing things? Flying. My dreams are fraught with tension.
