I think it's called Imagination

Journey into a world unknown
where reality is weird and wild;
into that place where pixies roam,
a kingdom ruled by wayward child.

Come with me and be set free
for soon you, too, shall find
that this glittering world of fantasy
exists within my mind.

Be still my darling, no need to fear
that which you cannot explain
for soon the dark will leave us here
and light shall heal the pain.

Carry on, into that strange wonderland
of crystal hopes and liquid dreams.
Please, do not try to understand
for reality here is rarely what it seems...

Take the steely, silver knife
and swiftly pierce my heart,
for in your hands I place my life
and love shall never part.
