Greetings to a fellow night owl ;-)
39a is 'subconscious'
However, I think that you might need to change some of your existing answers.
I suspect that 27a should be 'magnetometer' which doesn't fit with some of the letters you've already got.
Similarly, I can't believe that the English language can have more than one word for 'the act of throwing something out of a window'. The only word that I've heard of is 'defenestration' but, once again, that means you making changes to what you've already got.
