First things first. Wicca is a religion. You say you've been studying it. Then you go right into spells. Are you studying Wicca or witchcraft?
Now, as far as magick, looking at the spells, you have to keep in mind that magick goes with nature, not against it. So no, no turning into anything. Love spells do exist, but I question the use, as I would consider it false or forced love. But nothing wrong with wanting love in general spells. As far as raising the dead; no. But you can talk to them. And here's one, don't you think if we could get rich with money spells that there would be a lot more rich people?
So there you go, use common sense and you'll be fine. Blessed Be...
