More information:

It is possible to wake yourself up from a bad dream. You can also change the way a bad dream ends. This sort of awareness while dreaming is called lucid dreaming.

It can help to tell yourself, before going to sleep, that you will wake up when the dream occurs. This takes practice, so do not be discouraged if you can't do it right away.

To wake up from a bad dream make yourself do something physical like running really fast or turning over and over. The attempts to do so will make your body try to do the action and the movements will wake you up.
