Does anyone have difficulty trying *not* to fly?

To put it shortly, I had a lucid dream last night, and when I realised that I was dreaming, I did the natural thing and started to fly. But then I remembered that I had intended to see if I had a dream guide and try and meet my dream guide, but I couldn't get back on the ground. I managed to fall to the ground a couple of times, but I bounced off the ground and back into the air again. Other times, I would swoop just above the ground and then float back up again. It's kinda feels like gravity gets all screwed up for me.

Does anyone have any tips on how to stop flying once starting? Anyone else had this problem? It seems that walking normally is harder for me than flying in my lucid dreams!

(I posted a full report of the dream in my journal; Dream 024: "Above the Forest" if anyone is interested)
