Thread: Brilliant but stupid ideas

Do you ever come up with this brilliant idea in a dream, only to realise that it was incredibly stupid after you wake up? For example, from my dream journal:

I saw a sign with some German word on it. I noticed that the word was a compound word made from a word I can't remember and the word "semin", which I read in my head as "semen". I went through a door to the right and saw one of my maths teachers. I suddenly thought of this amazing idea do to with the compound word that she might be interested in, so as I walked with her up a flight of stairs, out the building and down a grassy hill, I explained to her this phenomenal thought: "You know that word outside? For example, take the word... 'officestaff'. It's a compound word made of the words 'office' and 'staff'. But what if the word 'staff' had a different meaning than what you expect it to be?" What came to my mind at this point was a magic staff.

Have you ever had a brilliant yet dumb idea in a dream?
