i too have had similar dreams and they have increased in frequency in the past few years. it does seem to take a certain amount of focus to be able to get up, but once i'm up, i'm there. although, in my flying dreams i am afraid that i will fly to high and not be able to get back down to earth. it seems as though i get too frightened to go any higher. when i realize that i am safe i transfer into an euphoric state. after discussion with my father, brother,and sister they have the same flying dreams and the same feelings throughout them. oddly enough, the majority of the time the dreams start in the same place. (childhood neighbours front yard). they are in the same location for my sisters,father,and brother as well.
