I have fantasized a lot
If I had a Pikachu
If I were in Xiaozhi's world
If I also had a Digimon
If I discover my soul egg one day
if if
Until my thoughts are confused
Fantasy: unrealistic imagination
unreasonable wish
But these definitions do not really define what fantasy is.
In other words, these are not fantasies at all. It's because you haven't seen them or you just can't believe them.
Then... Do you believe this?
