Secret Base in Dream Realm?

I’m in the dream realm and after the first battle with the pokerus virus (no spoilers) and realized I really need the Level Trainer from the secret base. Is there any way to access my secret base from the dream realm?

No as far as I know as there are Chanseys instead of Pokecenters

(Correct me if i’m wrong)

yeah you are correct, and that is what I was dreading, I hate grinding because my team consists of medium-slow levelers.
