got a few times experiences.. one time is too sick, then the
rest should be dehydration.
for my cases, just saw blackness & nothing else, thou' my eyes
are open. Not fainting, just cant c anything..
I realised something, if blackout, dont squat down, if possible
(still conscious), remain standing (not walking).. & hold on to
something or lean against a wall if there is one.. cos blackout for
my case is just a short moment.
