I can’t remember when I had this dream, it was a few months back. But I recall running down a hall way in what appeared to be my high school at first. As I was running I realized I was dreaming and told myself to slow down and take in as much information as possible in case there were importance in the detail. When I looked at the walls they were made of glass and I could see weird sculptures. Then in the next hall the Walls were also glass but were filled with fish.
This is a cool dream and a great application of exercising control in a dream in a way that does not change it but enhances your ability to understand it. By slowing down, you allow yourself to better examine what it is about your past that God is wanting to talk to you about. This dream indicates that on your journey God has always been calling you to see things in a way that others did not. In some ways this has been easy for you, but you haven't always "slowed down" enough to realize what it was that God was doing.
