Yes I have. I find sometimes im in a day dream. Im awake but lost to whats around me. Sometimes disturbing but not always. If im tired or stressed it can get worse. Also like nick says when your falling asleep. I try to shake it off and continue. I also have dreams and in my dreams I'm telling myself to wake up. I then dream that I woke up and it wasnt a dream. Scares the heck out of me. Lol then I do wake up im relieved it was just a dream. Not a good way to start the day.
