Dragon's new form, her shadow or nightmare form. In this she is able to take out dreams and eat them. She normally goes in this form to help someone get rid of a nightmare

In her hand is a nightmare. If she let's it loose, it can come back. So she eats it

After she turns normal, she throws up black goop. The nightmares, most of the time, dont settle in her stomach and makes her vomit it back up. But it turns into a liquid thats sorta sticky

She could fight in her nightmare/shadow (i havent figured out which one to call it) form but she never tried it out yet
