¿y si todo esto no es más que un elaborado sueño?

Es una pregunta que todos nos hacemos alguna vez.

Supongo que esa duda sobre que nuestras percepciones y sentimientos sean un engaño va unida al ser humano desde que tiene uso de razón. Al menos hay un buen montón de obras que hablan de ello, desde La vida es sueño a Matrix. E imagino que parte del atractivo que tiene es que nos inunda un sentimiento desesperanzador, pero también de consuelo, pensar que lo que nos pasa y nos rodea no sea real.

Me quedo sobre todo con el poema Sueño dentro de un sueño de Poe y con una canción reciente del Sr. Trent Reznor.

Nine Inch Nails - Right Where It Belongs


See the animal in his cage that you built
Are you sure what side you're on?
Better not look him too closely in the eye
Are you sure what side of the glass you are on?
See the safety of the life you have built
Everything where it belongs
Feel the hollowness inside of your heart
And it's all
Right where it belongs

[Chorus:]
What if everything around you
Isn't quite as it seems?
What if all the world you think you know
Is an elaborate dream?
And if you look at your reflection
Is it all you want it to be?
What if you could look right through the cracks?
Would you find yourself
Find yourself afraid to see?

What if all the world's inside of your head
Just creations of your own?
Your devils and your gods
All the living and the dead
And you're really all alone?
You can live in this illusion
You can choose to believe
You keep looking but you can't find the woods
While you're hiding in the trees

[Chorus:]
What if everything around you
Isn't quite as it seems?
What if all the world you used to know
Is an elaborate dream?
And if you look at your reflection
Is it all you want it to be?
What if you could look right through the cracks
Would you find yourself
Find yourself afraid to see?
