Only a few people can and / or want to be lonely.
 The average person needs to communicate with other people. If this doesn´t work, he's looking for a replacement. In the first place today are the pets, which are then often not anthropomorphized.
 In the past, pets were not common and therefore people look for “replacement-beeings”. Regardless of cultures, beliefs or ages.
 As a child I did not care if the stories of angels are true or not. They were told by the elders, so they were real.
 At a time when there was no way to check data, in a time of almost infinite loneliness on the remote farms in Iceland, the presence of elves, trolls and hidden people is completely human.
 The current wave of isolation due to lack of direct communication, due to the extreme media consumption as well as the impersonal mobile phone use - the same picture on the bus ride back to Reykjavik as anywhere in the world - revives the replacement communication with supernatural beings.
 Elves, trolls and hidden people will not die out here in Iceland!

I really enjoyed the story telling and that attentive listening and in the meantime each creating someone’s own pictures in his/her mind is what should get revived in school as well. Let your mind create pictures from what you hear. Challenge your thoughts, memories and attention and not just being spoiled with ready made pics. 

Besides, from now on I will actually blame some elves for any of my lost things I cannot find anymore. That was such a good idea to have an excuse!
