Myth or Truth?

I am a fish in a glass bowl,
long dead but I still have to
dance to your symphony
each time you pipe
the flute, each time
my mail box clinks.

I am an ostrich without
its head; my mind lost
in the sand each time
you draw a magnet
across my lips
to make it pucker in a kiss.

I am a unicorn, myth or truth,
now extinct but tease
to life by your breath
because you never know
I am dead.

Note: This one should undergo a major revision but I'm not sure how I should go about it. I think I'll workshop this at PFFA.
