I don't believe you can physically ever see faeiries through our eyes.

However I do think we can see what the fairy folk look like through psychic impressions in our minds eye. And that these impressions can be channeled onto pen and paper through our art work. And many people have already done this. The tarot deck by Froud and and the Fairy Bible by Moorey. I accept that these really do contain pictures of what these faeires actually look like and I believe that.

To explain why I believe this I will tell you about an experience I remember having when i was having a snooze lying down on the bed at my boyfriends house which we both think is haunted by a girl for various reasons which i won't go into.
Whilst my eyes were shut I had, a psychic impression of a girls face, face to face with me. !! It didn't scare but I do remember thinking where did that image in my head come from. It was completely miles away from my train of thought and I've never seen that face before.

I think the faries can send us impressions of themselves if they choose to just like this
