What if the Lock Stress Monsters are shape shifted forms of the Dream Keep Dragons? Should they be a completely separate thing, or should they be connected?

If part of same characters and universe: 
In their natural forms, Dream Keep Dragons protect dreams, and keep them safe. However, emotions are deeply tied to dreams and somethings you need to go through them and work them out in your dreams to process. 

When the dream Keep Dragons come down from their Comfort Kingdom they must always cross the vast ocean of emotion. To not get dragged down by the power of the raging waves of emotion, they must shift into the Lock Stress form. 

They can sense and seek out the person who needs them most, and start in their small pocket form so they can be there for the human calling to them. However, as they grow with love just like their dream defender form, they can also grow into their “Emotion monster” form. Large enough to help you calm and settle your strongest emotions. 

What do you think? Should this be tied to the dream keep dragons as their water forms? Or a cousin ajacent to the lock stress monsters, like how there are “Sea Ponies” in my little pony?” Or should they be something separate all together?
