You can't retrieve or recall something that hasn't been called upon. That's what activation is for. For you to call it up for the first time so it can be recalled in the future.
I'm asking my unconscious mind questions and presenting concepts
I find "concepts" weak and useless request of the non-conscious mind. Concepts - general idea, notion, an abstract or general idea inferred or derived from specific instances.
That's like trying to catch a cloud with a butterfly net.
Make your purpose request something concrete. Specific. Asking your mind for a concept is like asking for "food" when you want dinner. Your mind then points you to the fridge and says here's food and you say... that's not what I want... I want food food, you know real food.
Make your order clear. Your conscious mind has difficulty recognising a concept when it's offered to it.
