Have you ever had a dream where you were in total control and aware of what was happening?

I have to write this down before I forget. Last night I dreamed three seperate dreams and actually told myself to wake up or leave the place in each dream. The first one I was floating in some type of office with glass walls and I kept slamming into the glass and the people who were in the offices were beginning to stare at me and looked pretty annoyed with me and I told myself I think it's time I leave here and floated awau I woke up in bed in the early morning. I went back to sleep and found myself at this party outdoors at night outside of this large house where candles were lit in trees and people were sitting, some talking, some listening to this woman sing on this dimly lit small stage. I stayed for a little while wallking around then got bored and told myself it was time to leave and I floated up again and even looked down at the scene while doing so and woke up and it was 430am exactly. I rolled over went back to sleep and then found myself in some type of library with a middle-aged black woman sitting at a desk asking me if I needed some help. I told her no, I don't belong here and it was time for me to wake back up--this is the really weird part. I concentrated in the dream on waking up and ended up instead in an aisle of books. I remember saying "damn, let me do this again..." then said "it's time to wake up...wake up!" and I did and it was 6:11am on this Sunday morning. So, my question really is what does it mean when you are this much in control and aware in a dream? It just seemed so real to me. I've had these types of dreams before but never in sequence like this.
