Your poem made me reflect on how interesting it is that we talk about our dreams as living and dying things - as through they are alive and can die. I know we personify a lot of things, but this is a rather consistent personification. I wonder why we bring our dreams to life, and signify their loss as death.

It felt like you used darkness in a few differing metaphors - you are in darkness, darkness hides things, death is darkness, darkness is moving in against you will, etc. Your last line seemed to tie them together nicely - "Death truly hides in the darkness".
