Fairy Schools

Always take claims like that with a grain of salt. If someone claims to be a fairy or anything similar to that then be careful what you believe from their story.

'So are those girls on youtube lying about their experiences?' yes, yes they are. people can lie.

while there are people who work with faeries and believe they are real, they are not physically real. they're more like spirits, and can influence situations/people with their natural abilities, but they too have limits. a fae could bless/curse someone, but they cannot transform them. real magick works with nature, fae are seen as nature spirits, they [as well as magick] cannot contradict nature. [even magick has limits]

if you wish to work with faeries, the most you should spend your money on is a reputable book about a faerie magick path [ https://www.llewellyn.com/product.php?ean=9780875427331 might be of use] otherwise, you can research online, try to connect with them on your own and build your own path [start by making a faerie garden. big or small, it's kind of like an altar for the fae where they can stay, and you can leave offerings]
