You push any creature you touch into the Shallows physically if it fails its Will saving throw. However, this visit is not idyllic—the creature permanently relinquishes its ties to the waking world and becomes but a passing dream with a life forever bound to dreamland. Should the creature ever seek to pass the boundary between Dream and the waking world, it disperses into nothingness as if a dream forgotten upon waking. (Note that the creature remanded to Dream's fatal embrace does not gain the dreamborn subtype—it is too ephemeral for that benefit.) Worse, without the Lucid Dreaming feat, the creature pushed into Dream soon forgets its identity, abilities, powers, and possessions.
Only through the use of the dream birth power can a creature remanded to Dream's fatal embrace return to the waking world without dispersing.
A creature that makes a successful Will saving throw is partially affected and takes 6d6 points of damage as its corporeality partially transforms into dream substance, which flashes away like steam. If this damage reduces the creature to 0 or fewer hit points, you still transform it into dream substance.
You cannot manifest this power on dreamers or creatures already physically present in any dream environment.
