Like Im not talking about regular dreams that weird stuff or diffferent things happen and you dont question this new reality. Im talking about the mind actualy thinking about it and believing it.
For example I had a dream last night I was in summer school for Algebra (in real life I passed) but I was looking around at the class and I thought it my mind, "This is the exact class I was in when I took summer school for geometry. (untrue) and then my math teacher was there and I told him that it was such a coincidence that I had a dream that he was going to be our summer school teacher (again not true). So why does the mind sometimes do this? Like I had dreams also in the past, not very common though, but ones where a place I remember being before but I really havent and etc. Anyone know why?
