Of Life and Death

It was my grandfather who stood at the door.
"Grandfather !?", I said.
With faint moves he entered the room.
He opened his mouth but could not speak
and looked with begging eyes.
I'd heard he was traveling 
to meet his family for a last time.
I invited him to sit down in a big armchair,
but he seemed not comfortable. Tired.
So I asked him to lay down,
and in the mean time I prepared a meal for him.
Then I woke up from the first level.

I was lying upon my wife
and I made her pregnant,
and then I met my wife for the very first time :
she stood in a crowd and was dressed in a purple robe.
When she saw me, she looked scared.
She quickly turned away from me and froze.
I walked up to her and stood behind her.
I saw a tear on her cheek,
and when I took her hands in mine,
she shivered and I squeezed firmly.
Then I woke up from the second level.

I went to my office and sat down
in front of my computer screen and 
I wondered : how many levels can there be ?
