HealBot is a raid frame. Did you're raid leader invite dreamwalker into the raid? NPCs can't be grouped with players, they can fight along side you, but they still are not in your party or raid.

If you're responsible for healing the big dragon, just heal the big dragon. Your raid frame takes up like 10% of your screen, the boss takes up about 80%. It's a big dragon, you shouldn't have any problem targeting it.
