A Tangled Thread Inside my Head

I walked into a hazy area.
Was it a room?
Was it an outdoor space?
Or was it actual space?
But I was too preoccupied to care. Because across this infinity, I spotted a dark figure. I approached the only sign of humanity that I had in this environment with interest. My heels clacked on whatever floor there was if there even was one.
This figure was now in turn approaching me.
My heart pounded.
This person could be dangerous.
They could kill me. No one would ever know.
But inside I felt a compelling reason that everything would be ok, and that it was actually necessary to meet with this person.
As this body came into view I realized that there was a striking resemblance and familiarity about them.
I then realized that this figure was another copy of myself however this copy was male.
Out of nowhere this blue line that seemed to go on forever, shot between us and settled on the ground to a dim glow on the floor.
We looked up at each other and pantomimed for a second before in unison asking
"Who are you?"
We then each walked across the line simultaneously and I assumed his position as the male version of myself and he assumed the female version.
I felt myself up in disbelief and realized he was doing the same.

And then I woke up.
