if you are imagining your mind, you are imagining your mind.
to me it really is as simple as that.
but as sad panda delved into, it really does depend on one's definitions of who or what defines "you" and "mind".
though i will add,
mind is not the same as brain. Your "brain" is the large internal organ in your cranium. Thinkers of all kinds have tried for millenia to pin down what exactly "mind" is.
"consciousness man!"
edit-
that first sentence could also read as:
if you are imagining your mind, your brain is imagining your mind.
or;
if you are imagining your mind, your mind imagining your mind.
