The Merchants of Sleep

Psychology is an important science. We all have to dream at night. Therefore, when one cannot dream, there is a problem. In order to sleep, you have to be in a warm place. That is why we need energies like gas, electricity and solar energy. There is a belief, that there was a Queen, for who they had to look for sleep and the solution was to offer her cattle, that make milk. Sleeping beauty is also a fairy tale which reminds us the story of Romeo and Juliette.
