Try not to think about anything for more than a
second or two by constantly switching your attention.
This simulates your thinking patterns when you are about
to fall asleep. Once you have done this for long enough,
the images and sounds begin to take momentum on their
own (this is called hypnagogic imagery) and get very
strange and illogical. You should enter a dream at about
this point and you will probably become lucid quickly.
Otherwise, you will eventually realise you have entered
sleep paralysis consciously (see above).
