What might a dream be ?

What is a dream? What the lucid dreaming could be ? So far, science has failed to clarify this questions.

Is the dream only an electrical activity of the brain and/or a result of the motion of the eyeballs ?

Could the dream be a journey of the spirit throughout another level of reality ?

We certainly do not know the true nature of the dreams and, because of this, our curious and imaginative minds have plenty of room to play with this topic.

Starting from this premise, "Inception" challenges us to ask ourselves if we could enter into the dreams of other persons, in order to steal their ideas or to implant in their minds ideas that are not actually theirs. Could there ever be a technology allowing us to do this ?

The film is a challenge for our speculative intelligence. To those who haven’t seen it already, I do recommend to watch it. Once or even twice. For my part, only at the second view I understood (probably) all the debated ideas.

Dreams seem quite real while we are inside of them, right ? Only when we wake up, we realize that there was something strange there ...

Is true that you never remembered the beginning of a dream ? You always just found yourself there, in the middle of the action, right ? Our life works, more or less, the same…Does anyone  remember something about his own birth ? No, because we all remember our lives at a time when they had already started…

And the most bewildering question of all:

When we die, we actually wake up? Is this life only a dream, a simulation? (Even if would be as so, we shouldn’t forget that any awakening must come from an external signal or from a signal transmitted by the body and not as a result of a desire intended by the  sleeping consciousness...)

As a brief conclusion: from now on, when you fall asleep, remember to take your totem with you.

What is a totem and how to use it ? You will learn by seeing the movie.
