Your twin flame is calling you. This happended to me on 11/11/2017. The entire day my thoughts were flooded with 11:11, twin flame, etc. I had never heard of this before then.

People interpret twin flames differently. Some think it's your higher self connecting with you. Others think it's soulmates (male and female). I like to believe it's the second one based on my experience. I got the impression my soulmate was trying to contact me. Because only someone in this dimension would care that it's 11/11 and not some other time. Higher beings aren't limited that way.
