Seeing names in places is so common when Im thinking about someone.
its basic IM. but it doesnt mean "here - this is a sign that he is the love of your life" but rather "here is a reflection of your thoughts, the universe is miroring"
My life has proven to me that "signs" are not meningless but they do not answer the question "Is he my soul mate", if I focus enugh on something or someone I will manage to manifest them them in my reality somehow.
Heres an example: I was once really into a man I had a breif encounter with and was living 900 miles away (the second I saw him I said "I found what im looking for".) I had so many incredible "signs" about him and he was just what I (thought I) wanted.
After we spent days together, he was back in his counrty and after about 2months of not hearing from him, I was missing him and one night I was really meditating about him, praying, asking for signs and went to bed.
At 4 am a book falls from the shelf opening on a page that said "Love" in big bold letters, not 2 min pass and I get an text message from him, saying "Im coming to your country in 2 weeks hope to see you"
Well there was my "sign"! I was so excited. And he did come, even extended his stay, we were together everyday for a month. and it was amazing, I was sure I found my soul mate (and so did he) but even then I saw that I wasnt feeling completely comfortable with him.
Anyway, after that visit we met again, this time it was a disaster, this time the sitation was tougher for external reasons, and it was a nightmare! This guy was so unsuitable for me, like he was square and I was round. No way could we have had a happy life together.
What Im saying is that if I look back at all the signs Ive had about guys,
I realise that I cant trust them to answer these big questions (plus I believe we have more then one "soulmate"- maybe even 20).
The only thing I can trust is my body.
My body knows. If Im in a situation which isnt good for me or that is good for me, I will feel it in my body, that is real- and that is what I can trust.
So IMO you should not set yourself on one specific guy, but rather focus on what you want. write down the list of traits that are really important to you (not too many), and trust the universe to send it to you.
I would advise you not waste your time trying to interpert signs. All they mean is: here are your thoughts- made physical.
