Fairies

I did pick up a book from the shelves in the house and read a short description about fairies. They are like humans in appearance it said but living inside the earth. The dominant colours in their appearance are brown and green tones. Most humans do not see them. Humans who do see them are changed after that. They are neither good nor bad. The experience of time is totally different in their world. When you have passed in short time with them hundredts of years have passed in the human world.

Again that different time experience attracts my attention. 
It all sounds very familiar and with my imagination I can easily visualise what they look like. I like those different beings and different parallel worlds.

I also read a story of the seal-people. Who are seals but can also drop of their skin and appear as humans. I remember I had a dream of a seal man some years ago and shortly after that when I was swimming in the sea a seal did come very close to me. But when I became afraid of what might touch me under the waters he disappeared.
