Actually they left it deliberately ambiguous as to whether there was a monster or not, and I don't really have a problem with that.

My problem is where they ended up in the last part of the episode. They should not have been able to go there so easily, psychic link or not. And then Clara sort of ruins The Doctor's goal of finding that place again for no logical reason, other than it would be too easy maybe? I don't know.
