YA Book featuring a boy and girl and a parallel universe

[Michelle]

I would have read this book in the mid 1980s. What I remember is that the kids in the book would relax their bodies and then they would take three steps down (maybe at a tree in their mind) and enter a parallel universe, but only in their minds.
