Lately I've been miserably failing at controlling some of my dreams. Is it possible that I am just asking to much of my subconscience to create for me?

-One lucid, I tried opening a door, telling myself that on the other side, there would be a tropical paradise. I opened it, and I saw a nice boring hallway with more doors only to have a single room behind each one (like college dorms)

-Another one, I told myself, as soon I would jump through the wall, I would be a professional hockey player playing on my favorite team. I jumped through - and nothing. The best I managed to do was start a game of inline hockey no different then what I've played in real life

-Another one, I went into outer space expecting beautiful sights, only to to get lost in blackness and see the occasional non-realstic (though somewhat cool) planet. No super novas, galaxies or any of that.

I don't know if it's doubt, but I am sure a few of these times I really believed I could make it happen but it didn't. Am I just asking for to much right now? (Into my 7th month of lucid dreaming) It's not the "I can't fly, or I can't go through walls, or see clearly" type of problem, it's the "I can't make my own plot" problem!
