tennesseejudy: I wonder what triggers certain dreams. They seem to just come out of the blue.
Ok, I'll play...
The most logical explanation I've come across for dreams is that they are the conscious mind attempting to bring about order. Whatever issues you've been dealing with during the day that you were unable to solve, the mind attempts to make sense of them while you're asleep.
The dreams we remember are the ones that are occurring just before we wake.
everyone dreams every time they sleep unless you have a mind that is free of conflict and maintains perfect order throughout the day...or have an awareness of your conscious mind as the tool that it is and not mistake your thoughts for reality.
