there's nothing quite like surfacing after a night dive and just
floating there in the open sea, looking at the stars 
I usually get very antsy around this time after night dives
....
cos you know the really big ones move into the shallows to feed
at night right ? .....
late last year i was watching this documentary about this two
ang moh guys who lived by themselves for a year on one of the
islets around tioman, and they were saying how they NEVER went into
the sea after dark, cos around dusk, they can see HUGE shadows of
sharks moving in from the drop offs into the shallows and inner
reefs to feed ......
