Have you learned your basics? If not please learn them, you should not cast spells before understanding the basics. If you are trying to do spells such as, Vampire spells, mermaid spells, or anything of the like, you cannot. You are human, and always will be on this plane. No levitation, flying or anything of the like will work because it is physically impossible. Magic is not like hollywood movies, you cannot snap your fingers and burn things. Most of the spells on here are fake, only put up there by what we call "fluffies". Please use common sense to find what is real and what is not.
Here is a link to the Basics if you do not know them yet:http://www.spellsofmagic.com/read_post.html?post=280420
