Flying and Trying

I love dreams in which I can fly. I have them pretty regularly and they are awesome. I feel very free and easy and can go way up high and go really fast. Last night I was trying to prove to someone that I could fly but I couldn't! I pointed my chin up to the ceiling and struggled but it was exhausting and at most I could only get about 2 inches off the floor. Finally I got a little bit better but it was still much harder than the usual flying dreams. I think it was because I was trying so hard. Usually it just happens without much effort. There's probably a lesson in there.
