In my own experience I often find, particularly in conversation, that words pour forth from my mouth without me having to consciously think about them too much.

When analysing what I've said I generally do find it coheres with my 'thinking' on the topic, but at the same time it seems as if some pre-conscious or subconscious process is drawing these words up from the well of my consciousness without my conscious (thinking) mind needing to be involved. Do others experience this phenomenon?
