Clyde what i think she meant, was that the astral planes, or the other realms of the universe.
As to what has been previously stated, you yourself can not change your physical body, or do the kind of spells that has been claimed, ''witchcraft!''. That is impossible, no teleporting spell in the trick section, or any other section, for that matter will, work. Thus, yes there is ''astral travel'' but that too, is also hard to do, and can be a long time work dedication.
I suggest learning the basics. What magic is, and isn't. Also gbring yourself to be realistic here. Did you really think you could teleport? I thought you were, joking.
