What does it mean when we experience coincidences?

Question:

“A recent experience I had while visiting Paris has me wondering what (exactly) it was. 

While window shopping, I was drawn to a pair of sandals. 

I said while trying them on “These look like Cleopatra sandals.” 

Two hours later while walking on a busy street in Paris, something fell to my feet. 

I picked it up. 

It was a Cleopatra bookmark. 

I kept it. 

The next morning, with room service, a beautiful cat walked into our room. 

I asked her name. 

Of course, Cleopatra!!! 

Is there some kind of explanation for this?”
