How to do a Thought Download

Is there a recommended way to do a thought download? What I mean by that is should I be writing out full sentence thoughts as they are downloading from my mind or listing separate thoughts on each line of the piece of paper? The first one to me is more general and looks like one long paragraph of thoughts all over the place. The second approach focuses more on identifying specific negative thoughts (though some may be positive). Does it matter which way we document or structure our downloads?
