and they end up somewhere.

Yes indeed. That's exactly how our brain works. It functions like an everlastingly dry sponge always ready and willing to absorb everything and get soaked with absolutely every bit of stimuli happening around us. Even without us noticing it.

..when something happens and I know I dreamt it.

Yup! through dream states, when our brain is really in calm and our mind in rest. Those are specifically the brief instants and our best chance to unconsciously find the keywords to unzip the data and bring in the light of a semi intermediate state of consciousness all those events and experiences that were stored with a password by our brains on their own, during our waking state without us having noticed before. If you have had the chance to have these "written down as hard copy" so that they can be reviewed and examined afterward in a state of full consciousness. that explains to a large extent the high coherence, eloquence and rationality of your personality that is consistently displayed and shared in your posts. :)
