TF and alternate realities ?

I am currently at a part of my journey which involves deep healing. Separation will be 3 years soon. However I keep dreaming of my twin. In one dream last night it was like he was in another timeline and I contacted him. In the dream I was trying to get him to realise who I was although I had never met him in that life. It was sort of like a psst it’s me sort of moment, but as if i was popping in from a alternate reality. He looked slightly different and he was also with a girl that I think was me but she also looked slightly different to my regular self in the way she dressed/looked. Once I explained who I was we started talking and he “remembered me” but I was aware that we would run out of time and have to leave wherever that was. I saw 888 when I woke up. Im not familiar with timelines and that sort of stuff, could anyone shed light on what this could mean ? Any insight is welcome
