As far as I knew the only reason dreams didn’t have any details in them was because we were not aware we were dreaming . They seems so 2D to me and brief mainly just emotions and vague visual and sound. But I am confused now I was having a nightmare were I was on a train and it stopped at first I thought it was because of the snow then I realised aliens were ambushing the train (sounds funny but it was actually very scary ) then I actually become aware I was dreaming but still there was no details it was all just 2D then I decided to wake up because although it was without detail the emotions seemed very real and I was scarred because I knew that I was going to die (in the dream) if I stayed there any longer . So why if I’m aware that it’s a dream why doesn’t it seem as real as this world?
