Dude you need to learn meditation. That will probably help you to get control of your jumping. A human can probably teach you unless you know any non human beings that can teach you? Maybe when Milo does his music he goes into some sort of meditation.. Anything can help right? You definitely have to tell your uncle about the priest. That's so important don't leave a detail out. Then find an answer to this jumping thing. I think you're supposed to be some sort of cop for both realms.. Maybe something to look into once you get ahold of your jumping.
