There are some days when it feels like floating in outer space, apart from the everyday life. It seems as if you were alien to people and buildings, and the rat race for surviving is paralleled to a distant videogame. Actually it can be a glimpse of the real world, a sort of Matrix effect. When you try to say something an ancient song comes instead. Could be terrifying but you just sway into the rhythm and let it lead you. All is there and at the same time only your mind is real.
Some days can be harder. They can take those feelings away and leave you a ticket.
