Maybe ur too tired or ur already half aslp...
Smtimes when im on bed, on e verge of slpin, wil oso hear some
noise de... But tink dis noise is onli in my "sub-conscious" lah...
Onli i can hear... Juz got tat feelin tat e noise doesnt belong 2
my surroundin... Itz in my head...
Relax, itz ok de, dun worry too much.
