Starfolk experiences are passed down as genetic memory. Much of this information is accessed as dreams.

How it works. Everything the ancestors know or have experienced is passed (in varing degree) to the child. In humans it is weak, and you call it intuition, hunches, dreams, etc. In us it is so strong that it is just like an old memory. It gets dimmer over very long periods but it is still there. Memories may be anything from simple visual records of emotionally charged events (pleasant or unpleasant), to insights on cultural problems, all the way to specific understanding of the details of StarFolk technologies. There must have been job specialization among the Ancestors. Starman sees the engines almost perfectly (clear enough to have gotten a patent on the propulsion system!) but everything else is shimmery/fuzzy or not seen it at all. Grandaddy must have been the "Scotty" of the crew.

Search for home. We am homesick for a place we have never been to physically, but know very well. Back when we first came we told your ancestors about home. They called it Paradise, Heaven, etc. You may have a smidgen of that left in you, and get a warm, fuzzy feeling about it, and maybe a fuzzy vision about it, and you have never been there physically either. We're not even sure where it is, but we have some theories.

Potential problems. Having Ancestor memories can cause problems, whether the memories are subconscious or conscious ones not recognized as such. Buried memories are a source of fear and prejudice and can be very hard to change.
