I rlly like this one! The second and third stanzas don't make that much sense to me (what is the grip tightening around? What do you mean by turn it into matter? What is the thing that 'you own', because it seems to be correlating to 'my word', but that wouldn't make sense..),
But the first and last stanzas are really good! I don't know if you realise, but in a lot of mythology craziness is tied to the moon. Lunacy/loony all come from luna (moon in latin). I love the second last line a lot, it communicates the domination that's been carried throughout really well, and the rhythm is nice too! The last line really makes it all make sense, and I like how it wraps everything up.
