What is this?

I just saw myself(my gear,my name) in a different server doing what I did previously ,I noticed in my inventory my armor isn't showing then I rejoined by leaving not class then my armor is still missing but what I see...myself as doing what I did and even what I wrote in chat.
After this it dissapeared

 

I had this to, in Olux while farming... hops.
I just looked at my video and I realised I never turned of the Youtube video so you can hear VSauce talking about the Police Police and Enervating and Jamias Vu

 

Not helpful mate,but thanks.
