I am inexperienced in this and am trying to reach LD someday, but...

What if you made place (room), in which you`d have HUGE hourglass. After sand would run out you would awake. Now you should:

A) try to change your perception and slow the hourglass before it runs out.

or

B) make yourself so much faster in a dream, that the hourglass seems much slower, but despite you being faster, have things you experience at the normal speed.

What do you think?
