i think you can sometimes look too deeply into dreams. at the end of the day, we dont know if this dream means anything at all. and although no ones said it, it could just as possibly not mean anything at all!
personally, i fail to see how being unable to control yourself whenever you try and stand up or walk, relates to looking for a "new direction in life"
could it be there is something that you lack control over, but in wanting to control it, you keep going back to it, you keep trying to stand up, something always knocks you down, but you dont stop, you want to control it your way, and you wont stop until you have done.
dreams are strange huh? - i dont know how much i believe they are subconscious messages sent by your mind...although theres a part of me that does believe it to some extent, through experience of my own dreams! lol
