The Moon Eats Me in My Living Room

[tectak]

A silver bell hovers
above the skylight—
louder in the earth
than my ears.Because of the undoubtably "poetic" language used in this stanza it is easy to put intent away and just skim over the meaning. That is  a pity. There IS meaning here but it seems to escape you, too. You would be the first to comment if anyone else wrote "...louder in the earth than (in?) my ears". Neither you nor I have any idea what this means. Loud ears? Is "sounding" good enough? Your call
It sinks,
slowly through the ceiling
like a dime descending 
to the ocean floor Quite beautiful. The grammar is suspect and this time it is the grammar that one tends to overlook. You should say, " It sinks slowly through the ceiling, like a dime descending to the ocean floor" Yes?
then engulfs the colour Avoid the "then" link between stanzas. You have made a singularly worthy simile in the previous stanza. By adding to it with the "then" word you take weight away and make the whole thing lighter and less convincing. The "it" word in the previous stanza is indefinite enough....to try to carry "it" in to this stanza confuses and obfuscates. We are begging a question by now. What is "it"? OK...are we are happy that "it" is a bell like a dime that engulfs. Is that clear? No. Leave S1 as a cameo simile and start anew in S2. So: The slipping shadow engulfs the colour of (not "off". You cannot engulf off) my off-white blah blah blah...
off the off-white walls
washed in my lamp’s vanilla cast period. Same reason as before. See next line
and piece by piece Avoid the "and" link. As previous comment. Start the next moment as if it is new each day. Make the link by clarity and continuity of intent. That is always enough.
pulls the whole house 
between it's lips.
Only me and it remain— Double-schoolboy howler. Only me remain? Only it remain? Only I and it remain.....but even with this grammatical correction the structure leaves me cringing. Maybe " Only the bell (cloche, gleam, shadow) and I remain..." Your poem
a sunless earth Too late for cliches but not too late to mention
stalked by the moon.
I feel it's concaves concaves is not and never will be a noun. "I feel its (no apostrophe) concave curves"
colliding with mine.
like two tectonic plates
uncompleting each other, If you cannot find the the right word make one up? Uncompleting? Uncompleting? What on earth's surface do you mean? "Incomplete without each other...." Yes? If no, then I am lost and you are getting tired of the piece.
a hole inside a hole.

....but good. If I took too much time on this then it was not worth it. If I took the right amount if time, then it was worth it. Cut out the cutesy ommissions of capital letters after periods and go home happy.
Best,
