The first one I had, I was sitting in a row boat in the middle of central park. I realized I have never been there for some reason, and knew I was dreaming. I tried to make a rowboat in the distance catch on fire, but it exploded and I woke up.
The second one I had, I was in an all white room, that had a wall covered in clocks. Somehow I realized I was dreaming and tried to summon Salma Hayek, but I couldn't remember her name and woke up.
