If you eat at night before you go to bed, try to write down what you are eating to see if this is the cause, also do the same thing with TV programs. You may also want to try, writing down worries and stresses and fears.

This could be something that you need to take care of and have been putting it off and the dream is a way for your subconscious mind to get your attention. And also write the dream down and try figure out the meaning behind it, and don't go too deep with the meaning. Dreams are usually very basic and are here to help, even when the are bothersome.

When all else fells pray about, what have you got to lose---a bad dream.
