I do communicate with mine, and its language skills really stink. I'd rate its IQ about 60 or so. It's good at finding stuff, but terrible about telling me WHERE to look. It mixes up words, has an accurate vocabulary of fewer than twenty words. It can drive the car but not read the signs. It loves to draw and paint when permitted. It's partial to domestic animals. Not much personality though, overall; and that's fine with me.
Neither of us cares for ouija boarding.
My unconscious intelligence is rather similar to yours. In addition to the few, wandering skills it seems to have a keen sense of smell - and churns up memories when it catches a scent.
It is also very greedy, and will slip up images and messages about food.
