Had a Lucid-type Dream Last Night

I find dreams to be really interesting.
Sometimes when I am in between construction jobs, I like sleeping in. I'll set the alarm for 9:00 AM and hit the snooze bar 3 or 4 times. In between, I have one or 2 short dreams. They are like little movies to me of random things.
I read once that it is believed that in our dreams, all the thoughts are totally random and in no specific linear order. It is when we wake up that our brain tries to put everything in sequence. That could explain why they often make no sense.
Also.....Isn't it strange how in a dream, you could be doing or seeing something so completely impossible but you just seem to go along as if it is normal?
