Deja vu

How do you measure a deja vu?
By how many times you have one?
Or
How long does it last?
And can it be because what you are experiencing
Is not the same as before but rather a facsimile
Because a hug is a hug of a hug given 10 years ago?
Because a crooked smile gives you that shine of 11 years ago?
Because a laughter deeps in your mind like it die 12 years ago?
Because big eyes always mean something?
So, a deja vu is not a deja vu but rather a deja vu that tried to be one
I get it now...
