I think the most striking part of these dreams are simply how vivid they are. Somehow, I feel more awake in the dreams than I do when I am awake.
When I run in the dreams, the world seems to shift. Even though I am going fast (far faster than I normally could), I feel confident, as though there is no possible way I can fall. My feet just know where to go. I feel like all my senses are enhanced - smells are more pungent, my sight is sharper, etc. When I get out of that state, I want to keep running. It is like a drug. Usually, I am running on top of floating cubes in a void. Either I am being chased by things (I don't know how to describe them other than that. They have long, spindly fingers and their flesh is rough, like wood.) or I am running towards a glowing orb that rotates, suspended in air. I always wake up before reaching the orb or getting caught.
You also mentioned Max Spiers. I had never heard of him before, so I looked him up. I don't remember seeing him specifically in one of my dreams, but his picture looked so damn familiar. I can't quite place my finger on it and it's bugging me.
As for the dreams, I feel that they are quite a conundrum. I am always in danger, which I definitely shouldn't like, but I feel so alive when I run in my dreams. I've never taken cocaine, but I imagine the feeling to be similar.
