There's a word that describes a situation in which you have a new theme or a new idea in your mind and you find examples or nods or references to it in various places all throughout your day and regular life.

Things and situations have not changed but because of your thought your sensitivity and pattern identification towards it has changed.

I knew this word and it is now lost! and I can't even think of how to craft a google search term for it !But hopefully someone here might know.Dhanyawaad.

Perhaps Diegogarcity is the term that you seek?

Thank you. This is not what I don't remember . But This will do beautifully where I wished to use it.

A pleasure to be of some help

Welcome, monk. Synchronicity?

Edit: Afterthought--I wonder where the cities of Diegogar and Synchroni are?

Diego Garcia is a British island colony with American
Military Base on it. In the Indian Ocean. But I have
my doubts that is what is being spoken of on this
site. As for Synchroni, I have no idea.

Meshico?
