You catch a ghost by 1st saying it's locked like in an underground chamber or passageway. Then, you say it's actually in a friendly dungeon where it must be spottable.
The last of my dream was like a repeat. I think there was something to slide down or walk down with other people. It was like a march to get in the DIsne parade.
So, next, there was a friendly dog, it was my family and brother's friend. We saw the story, not so much the dog. It was like the top of it was an upside down vaccuum cleaner and it became the Vroom monster, kinda small or skinny. Then..well it had like 2 holes for eyes probably. We succeeded the 1st time. It was also about like practicing music, which I haven't much, and old music instructors, 2 sisters. So, it had like underground to go around, like Harry Potter.
