Random speculation: Dreams, a big part of our lives?

[Earthlover18]

I have been practicing lucid dreaming since last spring and now I usually have them on a one to two week basis. They are some of the most interesting and fun things that i've ever experienced. About 5 or so that i've had so far completely blew my mind. They lasted at least 10 minutes (in the dream) and I had full control over what I was doing; flying around everywhere, feeling the wind blowing in my face and trees rubbing against me as I flew past them, I even threw a truck down a road once.

One of my favorite things in my dreams is the sky. Usually in a clear lucid for me it looks like it has High Dynamic Range or something. I love Cirrus and Cumulus clouds so much.

Question: I'm sure everyone knows how you never know whenever a dream starts, but often you know exactly when they end. Do you remember the exact moment your life in this world "started"? I don't.
