And that's the sequence of my dream...
Tsunami heading towards my way
Unable to take the lift as it was chained by locks
Ran up the stairs
Saw a girl running up the stairs and gave chase
Reached tenth floor
And the rest were a blur

Linking all the key words... It does surprisingly form a string of attached meanings... Interesting... Everything little detail I remember in the dream seems to be so well coordinated... It's like there's a problem and a resolution at the 'end'... So weird...
