--"Before enter please think what is life for 5 minutes!"--

I did not have body any more,I was pure soul,and no one could see me.I flew out of my house and worried that how could I communicate with other people if I was only soul and no body.....I was in a big street,and there were many men,at least over 100,who all weared black suits like the men coming from the movie'Matrix'.They were fighting.I just watched them as an observor....Many pictures emerged in front of me,I saw the brothers of calabashes,Sun Wukong,superman...all the character in those picture were from fantastic stories of human being,these characters all possed super power.I sunddenly understood that in fact they were some kind of avatars of posthuman being which just comeing from the imagination of normal human being and appearing in the varies of stories,whatever characters they appeared in these stories they all represented the posthuman somehow which some people wanted to become--posseing super power....I was in a corridor and I saw a door in front of me,seemingly this was a lab's door,and I could clearly see something be writen on the door---"Before enter please think what is life for 5 minutes."

I had this dream in 2006 and at that time I was busy in my graduate thesis,which refered to some posthuman things.And this dream in somehow gave me some enlightment about posthuam things.Especially the last text appeared on the door,"Before enter please think what is life for 5 minutes".I think this door in this dream is a door of life science labratory.In the dream I did not enter the door,after I saw the letters on the door I waked up.And I thought"Wow.This is a meaningful dream,it gave me some clue on my thesis." Anyway what is life this is really a big question to me until now.From this dream I knew that thoughout the human history,the wish of human wanting to become posthuman in somehow having appeared in human fantastic stories,like superman stories.But what will happen if human being finally become posthuman being?What ultimately life is?Those "Matrix"-style men in my dream I think they also represent the posthuman being,although they already have possed super power there was still no peace among them.They still fought.So what is life?---This is a really big question.I think before anyone who want to have some experiments refeing to life especially posthuam experiments,this question should really be asked before enter the lab door or before entered the realted field or before doing any life experiments.
