Bad Dream

     I had a really awful dream this morning. After a night of tossing and turning and not sleeping well at all, I finally went to sleep about 6 and slept till 930, in those few hours I had a dream that has left me feeling sad and scared. Why do we forget some dreams the second we wake and others stay in our minds for hours and even days. I know there's a scientific reason for it but, what about the personal reasons? I only know that the ones I remember always seems to involve those I love, wether they be good or bad. This has to mean something but as I've said I don't know what. Are they warnings, guilt, deeply buried forbidden feelings, ?
