Why thank you, yes the poem is on a few levels, it is trying to portay sanity as both a mind set and a place, it is aout finding ignoarnance in bliss, that is why it says "no one wants to be IN sane" it can be taken as

1.) no one wants to be insane crazy

2.) no one wants to be IN sane, because they would rather be IN bliss, with ignorance

cheers to better days.
