"Deja vu" is a French expression, the feeling that one has lived through the present situation, literally meaning "already seen".
With this in mind I tried to explain it in verse.
The saying "Its a small world", no doubt you will have heard it said..
A feeling that you can relate to, suddenly comes into your head..
In your past the same thing happened, and then it pops up once again..
Something, someone or somewhere, it's difficult to explain..
There are lots of reasons for it, that bit I know is true..
It's how we tend to deal with it, and what it means to you..
Keep calm sit back and don't worry, it happens to us all..
When something from our past, decides to make a call..
