I learned that fairies like to eat milk and honey
That is an interesting book, but fairy are awesome.
Yes, they live with the mushrooms and dead logs and such in the woods but you can lure them out with sweet treats like honey and other offerings
Have you ever tried to lure one of them out?
THey visit me quite often. If I don't feed them regularly, they take my belongings and hide them until I do
I saw some where that they are spiritual beings like angels.
Yes they are considered a spirit. Fairies include many fae beings, like gnomes
Do they really make the feeling of joy fill your heart for a long time?
If that is what you want from them, yeah. Different spirits help with different things. It's also all in your head
Dancing around mushrooms or toadstools is that something they do?
