Wait... a garage full of zombies and I have to act as I do in the waking? Pfft, the situation is already inane =)

My dreaming is similar to yours, while I do not recall every dream most of mine I am consious and as I do now react in varying ways to the situation that I am presented with. Often I wont realise its a dream for some time but my instinct is to try and fly when in danger. On occasion I get into the magic/force stuff which takes quite a bit of effort on my part and a bit of figuring out. Like you I cannot help but to be consious but who is to say that I cannot use the abilities I have in the dreaming and not learn anything? The very act of being consious drastically changes any dream mundane or fantastic. Its the difference between watching a movie and playing a video game.
But as it was said just because my reaction might be to fly does not mean I lose any inspiration, feeling the break from gravity is an amazing thing. Sure you could react with grabbing a garden tool or chainsaw in the garage and fight off some of the zombies but when it comes down to it, if im gona get eaten I am going to do what I can to not get eaten =D

Sometimes I get eaten....

Other times that spark just hits me and I bash my head on the ceiling and charge the door or window in flight and break out from the enclosed environment of the garage over the gaping mouthes of zombies into the open world and then explore it. Perhaps its inane to you but to me its freedom.

I would also say the visions I have seen in flight will never leave me, nor will I forget the feel of the breath of the wind beneath my wings.
