This is all very strong, I like this one the best so far of all of yours I've read in the last few minutes

Great images and word usage.
I would only change the last two lines of the bridge - it gets to obvious again after being very ambiguous. I still got the point of the song without those two lines, and they seemed to stick out to me because I've heard them too often. Maybe just something simple like 'I've gotta be someone/ I've got to have a name" (or whatever you can think of that is slightly less lame

)
Anyway, again, good stuff!
