In my experience, it just doesn't work right.
Instead try to go there.
Don't create Hogwarts, instead go to the real Hogwarts.
I do this by leaving my dream bubble (just a bubble containing my current dream), and going to an entirely new place.
Doing so I have an easier time believing that I am in a real place, and not in a dream controlled by my own sub-conscious,
which renders dreams much more realistic.
