I definitely find this to be true as I dream vividly and frequently though usually with anxiety.

However I have also been watching a lot of dino documentaries and weeping a little inside at some of the bad info and the trail dragging when the footprint evidence was already there…

What does this mean? Last night I had a dream about playing a game about dinos and the score being how quickly your character could eat a stego before the other players and before the larger carnivores (NPC adds) came along. It was weird.
