I've felt this before, I think I've told you a few times about my connection with London. I chalk mine up to either past life or genetic memories. The Covenant Garden area impacted me deeply, as did Mayfair. In one way, shape, or form I had been there before (or at least my DNA had). I can't tell you how welcoming the thought of a cozy old pub is to me. I watch this wonderful channel on YouTube called, Loaded London, and just daydream.
I've also had moments of bliss where it feels as though time slows down and everything feels as though it's perfect. I remember about a year before I moved to Minnesota we had a snowstorm in Ohio, big flakes. I was walking at night and that blissful feeling came over me. It was like a huge hug from the universe, a reassurance that everything would be alright.
