Ok we all know that the echo allows us to look into someones memories, but what if the twelve themselves could contact us through the echo. This contact could be via these dreams and nightmares we are having.

For example the one where Van Darnus kills everyone, and you wake before he kills you, perhaps that is a raid that will go on against the imperial stronghold in Mor Dhona, and the twelve are showing us what will happen without intervention.

It could seem like the twelve are trying to help us, but they can only contact the few who have awakened the power of the echo, also in one cutscene I remember Van Darnus telling us that the twelve are not helping us, but what if it just looks that way because he cannot use the echo.
