I believe that is the term, in which during a dream state you can consciously control your actions. I have these types of dreams frequently, and they are quite cool. For example, I may be asleep at night and having a routine dream. Then at some point in the dream...I actually realize I am dreaming...then I realize that since it is a dream there are no limitations to my dream experiece. I may choose to fly or do some other super human feat, although I must say some dreams have had a more sensual realm, still there is no limits..except to your imagination. Has anyone else out there experienced these types of dreams?
