Once when i was little, me and my sister had the same dream. Every detail was the same. Do yo think this means anything?
If you were doing the same things before you went to sleep then it’s highly likely you’d each have a dream about it, the chances will be significantly smaller it will be all the same details, but not impossible…
My younger brother and sister had a shared dream where their grandma (not mine) tried to kill both of them, I remember that both dreams weren’t exactly the same but both also had a bike involved.
A few years later and what do you know, my grandma tries to kill my mom with a machete! 
Um, that is a bit personal information to share.
Anyways, I personally think that it could just be a sibling connection. My sister and I think the same things sometimes.
