A fantasy land

There was once a fantasic fantasy land in my mind.

It had a colorful sky and a floating islands.

There was once a fantastic fantasy land, it had a floating castle.

It had a king and a queen and both were me.

There was once a fantastic fantasy land and the kingdom was me.

It had people living in it and they had all met me.

There was once a fantasic fantasy land and all was inside me.
