Finally flew in a LD but...

Last weekend i promised myself the next time I had a LD I would fly. I realized I was dreaming last night and ran out the door and took a flying leap off the stairs and started flying. But about 20 seconds later I froze in the air, and the only way i could move is if I moved my arms like I was swimming.
I was wondering if that is common, and if there is any way to make that slowness / freezing go away.

I used to have that happen occasionally as well. It all comes down to practice and belief. You will improve at it I am sure. Just believe in yourself!

Somehow somewhere you probably where doubting. Try and overcome those barriers by convincing yourself that its all good and that you're dreaming.
