Oh dear me, that last line was a clever one, and a scary one too. This has similar ideas as the other one I read, memories and terror.
The descriptions of the "dusty floor" and "shadows" were good because they gave a creepy feel to the poem, which I guess is what you were going for.
Honestly, I think there are some flow issues with this one. It was mainly the first two stanzas that were off.
For the first stanza I think it was the wordiness of it that made me stumble, so if you could shorten it or break that up in anyway it may sound better. With the second stanza it was just the last line, and for the opposite reason. Maybe that line would sound better "when she's hurt" or something like that. Again, just suggestions, it's up to you.
Thanks for sharing, keep writing.
