Hey Tin, you sure you live in Darwhine? I know a bloke what lived/s in Cairns who was a bit like you, "gear up" and all.
His trusty side kick one night, sick of the never ending fuel calcs to determine if they could make TSV, all the while Skip was in the land of zzzzzzzzzzz, established the aircraft on glideslope down the 01 ILS and at a convenient time, pressed the GPWS Test.
Poor old Skip, woke with a start, to a screen full of lights, nose down pitch, and the GPWS screaming "terrain, terrain, whoop whoop, pull up, pull up.
I never did hear if he went to sleep again.
