I addition to my previous attempt (creating an ice bridge in mid air and gliding on it) I’ve given it another twist during a lucid dream last night. I still find it hard to think clearly during a LD and thinking outside the box for this task even harder, but anyway this was the best I could come up with this LD :

I had already been lucid for at least 5 minutes, when I remembered I could try to do the quest better than last time. After some thinking, the best I could come up with was trying to swim through the air as if air was water. I tried the freestyle stroke and was surprised how fast I was going and how real it felt. I could really feel myself pushing the thick air backwards with my hands to gain speed. I swam to end of my street and back again. Only my legs weren’t cooperating very well during the swimming, but failing legs happen to my quite a lot in LD. When I had returned from swimming 2 lanes the dream turned black and quickly I grabbed hold of some bushes and tried to smell a pine tree to not wake up. This actually worked and I managed to stay lucid a few minutes longer by doing so, which was a bonus.
I had some doubts about having completed the task on my previous attempt, but together with this 2nd try, I feel confident I actually did it.
