What's going on in my brain at this moment

What is it what is Deja Vu? Well I have the answer. Google says its A feeling of having already experienced the present situation. My amazing theory about what actually happens in Deja Vu is (you shall notice I have a lot of theories lol) that what if, I mean just imagine that there's two worlds or dimensions if you like, and so there's another you in a parallel world and Deja Vu is when they a line together because technically in the other dimension you are in the same situation however,doing different things but Deja Vu is when you and your parallel self do exactly the same thing in the same place. 


You see? right it works. But please don't ask where these theories come from my brain works in weird ways I could propbably give you a theory for everything so just ask ;)
