Long answer: There is a lot of fake, fictional spells and information on this site and, despite efforts to keep it at bay, there are many who are role playing or living out a fantasy. That being said, there is also some good information and serious practitioners who can help and guide you. The trick is to learn which is which. Discrimination, as far as what is good for you and what is not, is one of the first things you should learn on your magical path.
If it sounds like it came out of a fantasy or science fiction book, it is probably fake. If it claims to turn you into something other than the human you are, change your physical body or give you super powers, it is probably fake. If it claims to do something beyond the realms of possibility, it is probably fake. If it claims to make your dreams and fantasies come true by lighting a candle and saying a rhyme, it is probably fake.
If what you are looking at helps you to become closer to nature, understand it better, understand the energetic and divine principles behind nature, helps you to grow mentally and spiritually or helps you to achieve your goals by working with your mundane actions to get them, then it is probably real.
Do your research. Most people here will not give you the answer to your questions. They will point you in the right direction and help you to discover them on your own.
Magick is real, but the majority of magic you've seen in shows is fake. Magick is an energy source found in nature. It brings natural change by affecting the energy around us to attract/repel the desired change. It doesn't contradict nature or affect the physical in instant and dramatic ways. To cast a spell you charge the energy into your body, visualize your desired goal, and release the energy. After you've cast the spell, you work towards your goal. The spell makes achieving it easier for you.
While not every spell in the categories work, spells for love, luck, wealth, health, protection, cleansing, blessing, curses and death work, while "transform into" type spells don't. [grey area in magick would be beauty, death and weather spells. Some say the last two are too powerful for humans, while others claim you need more energy to perform them. As for beauty spells, they work by charging energy and speeding results as well as creating an illusion so people overlook what you want them to ignore] If you wish to work with magick, look into basic energy work and psi balls. You'll be able to feel the natural flow of the energy and be able to tap into and direct if so you can cast spells easier.
