reason for the name "surreal" and "hanabi"

[CREATE]

nice analysis guys!
you know alot of ayu's title don't make sense to me even til now:

poker face [what's the meaning]
TO BE [i couldn't find the relation between title & lyrics]
vogue [what's the meaning]
AUDIENCE
NEVER EVER
Daybreak
Free & Easy [the title's so carefree, but the song's dark & gloomy]
July 1st [was it written on july 1st?]
CAROLS [according to the title, the song suppose to be joyful, but it came out extremely desperate & sorrowful song]

someday i'll understand, that's for sure...
