To start with, me and my friend live in different countries, plus I don't know him irl.
Anyway, I had a dream that I was in my school, it was night time and many people were there.. I had this guy who was my friend walking and talking with me (talking to eachother) we talked about life in my dream.
When I woke up my friend said he had lots of dreams about me and I said I had one last night which is above^ he told me that he was in a school at night time with me walking down the corridor and talking about life..
I asked him; "What floor were we on top, ground or lower ground floor" he answered lower ground which was the same in my dream, when the dream came to an end he said something about our friendship etc.. (In my dream) then I asked him what his last kind of dream ending was like and he said the same of what happened in my dream ending..

I don't know my friend in real life, just online.. We've been friends for over 3 years.. I don't know what this is or what it means..
