I've never had the 'thunderbolt' feeling with a lover or DH, but I have with two people that I consider friends.
One was an elderly woman who was my grandmothers neighbour and the first time we met I just knew her, some part of my brain recognised her as someone I've known before somehow.
I can't explain it and I am not a 'woo' person but I don't have another explanation, although I'm sure there is someone that has a theory.
We had a close relationship throughout the years, but in my early twenties she became very ill, she had one son that lived in a different country so my family helped take care off her.
Two days before she passed in her sleep I was moisturising her feet and as I was putting her socks back on she stopped me and said,
" Thank you my dear one, I never thought I would have you again but your eyes are the same, so beautiful."
The second was a man a few years older than myself and I met him during a recruitment selection, we were in a mixed group of 8 and were completing some team building/GTKY exercises and we both couldn't take our eyes off each other ( non sexual) after introducing ourselves the co-ordinator asked us if we knew each other, we both paused, still not looking away until he mentioned that I felt familiar for some reason and shrugged it off.
We became very lose again, shared similar aspects of our personalities and thought process, SOH etc, we seemed to know what each other was thinking and would finish each others thoughts etc, it was weird and he mentioned the strange connection before I did, he was a very practical and logical person and I think he struggled with this.
Eventually he did begin to question it, one day we were eating lunch at our desks and a song came on the radio, both of us rushed out how much we loved this artist, he laughed and then told me about a book he'd read that discussed soulmates/reincarnation and in the book it describes how people who were family/friends in past lives finding each other again and how if that was true knowing me would make him believe this theory.
We didn't love each other, no lust but again familiarity and comfort just a sense that I was in the right time and space as him again for whatever reason.
I didn't have a thunderbolt of lust when I saw DH but I did 'know' I was going to marry him, I told a friend I was with and she scoffed because we are total opposites, but less than 2 years later we were married and expecting.
