Why do I feel like multiple people?

[Nnamzzz]

I'm not even sure if I should be here since the feeling lasted only 30 minutes.  But it was such an overwhelming sensation of thoughts that I feared if it came back I would be crippled for good.  

I woke up from sleep thinking that I was 2 people laying next to each other, then two people became 4 people.  One to the left, right, front and back.  And I was all of them at the same time with the inability to know what each version of myself was thinking unless I told my other self what to think.  And every time I got all of us on the same page, another version of myself would show up and needed to be caught up on my inner conversation.  What made these thoughts scarey as hell is that I began speaking to all versions of myself in the present, and then something happened that I couldn't handle.  I became concerned with all versions of myself in the future as well and I had to speak with the future version of myself.  So to speak to my future version, I had to wait until the future happened while remaining focused on my past thoughts.  When everyone was in the same page.  I realized that my past self had so many thoughts, that it was impossible for me to have remembered to mention everything my past self wanted to tell myself in the future.  So I had to re-think everything, while remembering to consider and inform all 10 versions of myself that we're currently in the room at the same time.  

But then it got worst....

I read a text message from my sister, then one from my fiancé... and somehow my brain merged the existence of everyone that I knew into a singularity of thought, and I felt as though EVERYONE I knew was aware of EVERYONE I knew.  And that everyone knew what everyone was thinking as long long as that information passed through my brain.  

This may sound concrete, and well explained, but honestly, this is the dumbed down version of what I truly experienced.  This is like the 2D frozen version of what I actually experienced.  My brain was honestly seeing beyond 3D.... it was like a 4D image, in motion, with a weird/abstract time space continuum with time moving in reverse, then looping back around, speeding up and slowing back down to normal.  

As I write, the feeling is gone.  But the memory concerns me.  I mm afraid it may come back.  Worst of all, what if people experience this 24/7.... it's literally IMPOSSIBLE to concentrate on anything.
