this is a great poem. The rhymes, the ideas, the imagery and symbolism found here and there, and the relation to the reality experienced in day to day living, by many of us.
No dear, you are not alone. And yes you are completely sane.
For the taste that you have for creativity, cannot be shared with people nearby, lest it loses its value. but the very taste, when it fashions such creative pieces, is not alone at all, hell it's not. You join with it the intellect and the wing-hearted.
