Ryann and Elodie will both be able to shield their dreams. They will be able to protect them from outside interference, preventing others from altering them using abilities like hypnokinesis or dream manipulation, even preventing people from spying upon their dreams. They will later learn to block bad dreams which occur naturally. However, they will not be able to control the contents of dreams more finely than that, unlike lucid dreaming, and they will not be able to affect the dreams of others at all.
