Dream Interpretaton -- Dreams of sin.

What are dreams? What do dreams mean? Please respond cause I want to know your thoughts. Some say they can see into the future, others claim that it taps into the subconscious mind and depicts fears or dilemmas that are present in life. OR dreams are just dreams, shows inner desires or just random stuff. I believe in all of the above, occasionally I get dreams that convey my desires, fears and problems. So last night I had a disturbing dream and I'm not going to get into detail here or let anyone really know. This isn't the first time I've had this specific dream, it's actually the third time in the past month or so. Reoccurring dreams usually mean there is something bothering you and it won't go away until the problem is resolved. I know I need to figure it out quick because last time I had several consecutive nights of dreaming about the same thing to the point where I woke up at 2 a.m and couldn't go back to sleep. The subject this time is FAR worse than my previous encounters. It's been irritating me all day, the solution sounds easy but very hard to go through with. I feel its depicting my fear, but in reverse or maybe it's a sign of neglect, trying to find affection and/or attention in my dreams.
