This poem is written fairly well. The comparison of a dream to a jewel is great, encompassing its mystic nature. However, you also compare it to a bird, a free being, which could insinuate a connection between the bird and the jewel, as both are an expression of the dream. Yet they are very different things. The bird lives, the jewel is but abiotic.
I believe though that you are showing that the dream is a bird, that the jewel is not the dream, but what can become of it. With "a sword can be made with jewels" you nicely express that through the development of dreams, we give our life purpose, and that purpose becomes realized through the actions of the one who forged it. Nice spin on "you are what you eat".
Sorry about the slightly analytic nature of my response. Thank my English teacher for me responding in such a manner. Overall, great poem!
P.s. Word "wich" on the 7th last line spelled incorrectly.
