Time travel and seeing yourself?

I had a weird dream the other night and was wondering if anyone else has had similiar dreams. I forget all the details but I traveled back in time just a matter of a few hours. Anyway there seemed to be a problem (I don't remember what the problem was.) Anyway I was pretty much in the same place at the same time separated by a short distance. I remember dreaming of many surprised faces to see me enter a building when I was already there. However the me that was there seemed to be a different timeline which I had not experienced because I was wearing something else.

Suddenly a mysterious blue or red glowing portal appeared and I watched the alternate me disappear into it. Then I continued on as normal with just one of me. However I got a voice telling me in my dream I created a time paradox. Everywhere I went this glowing blue energy portal kept popping up every so often scaring the living daylights out of everyone except me. I knew how to deactivate it but didn't know how to stop the stupid thing from appearing again. I also didn't know too much about where it would take someone. Weird dream. The best I can theorize is that my imagination combined some imagination with a computer game I played years ago. Anybody ever go back in time and see themselves doing something different than they actually did?

Not yet...

But i'm expecting something like that any time, now!

WOW

I am not asleep...I am not dreaming...I just found 3 more of me!

THREE!

1+1+1+1

That makes 4!
Open door.
