What is in a dream?

i have been having weird dreams lately. so here is what one website says about recurring dreams.

Recurring Dreams
Most dreams contain messages that serve to teach us something about ourselves. Unfortunately many a times we forget what we dream about as we go about our daily routine. With recurring dreams, the message may be so important and/or powerful that it just will not go away. The frequent repetition of such dreams forces you to pay attention and confront the dream. The dream is trying desperately to tell you something. Such dreams are often nightmarish or frightening in their content, which also helps you to take notice and pay attention to them.
Recurring dreams are quite common and are often triggered by a certain life situation or a problem that keeps coming back again and again. These dreams may recur daily, once a week, or once a month, but whatever the frequency, there is little variation in the dream content itself. It usually points to a personal weakness, fear, or your inability to cope with something in your life - past or present.
The repetitive patterns in your dream can reveal some of the most valuable information on yourself. It may point to a conflict, situation or matter in your waking life that remains unresolved or unsettled. Or some urgent underlying message in your unconscious is demanding to be understood.
