1111 is the Universal wakeup call. It’s a spiritual sign. When you see this sign, it’s alerting you to something spiritual in your life. If you have met someone and they have activated something spiritual in you, you will see this number sign as well as likely a lot of other synchronicities which is the proper name for such signs. If that someone is a soulmate, then yes, if you see this number it can be thought of as a ‘soulmate’ number. It can also be a ‘twin flame’ number, or just a number of spiritual advancement.
You are surrounded by soulmates in your life. They are the important people, your friends, family, lovers, compatriots, even your work nemesis who is there to give you a hard time. You share soul contracts with these people to share parts of your life with them. They will not be particularly transformative and you may not see 1111 with any of them. If you meet someone and start seeing 1111, it’s more likely they are your twin flame, who is you, your soul, incarnated in another body, and you have met to give your soul an experience that can only be had this way. This experience is truly transformative, disruptive, emotional, heartrending, and difficult. If you see 1111 and it seems to pertain to a person you have met, this most likely is telling you that you have embarked on a spiritually transformative ascension journey with them.
