Last night I was having a dream, and at some point in this dream, it was me, my little brother, and 2 other DCs. So, me and the other two DCs start to walk off, and my brother is sort of left behind. Now, for some reason I woke up, and my little brother was on the other side of the room sleeping. He sleep talks sometimes. About a second or two after I woke up, he said "Wait for me"

Now I don't know if he was having the same dream or not... but could have been. Not really proof or anything, but I found it pretty odd.
