I am VERY familiar with reoccuring dreams, but that is the topic for another post. I am going to take this from a psycological ( as opposed to a Psychic) perspective. I know that is not the stated purpose for this board, but I feel it necesary. I hope you all do not mind, especially given my newbie status.
I think, first of all, that the setting of a hostage situation is merely your mind finding a way to express itself in accordance with current events. The war has alot of people on edge and its constantly playing in the back of your mind somewhere, am I right?
I think this dream is in fact about your relationship with you family. Are U going through rough times at home? (Rhetorical question; not my buisness, just giving u something to consider).
You seem to be feeling like an outsider from your family unit. Your trying to attract the attention of the TV crews or whatnot is really U trying to attract their attention, love and support for whatever trying times you may or may not be going through.
On a slightly different variation, it could be that the hostage situation reflects on possible feelings that U are trapped by your family. They wont let U do what U want/need to do. Maybe there is some rather large decision that U have made that they are against and all U want is their support.
In regards to getting rid of this dream, I would say write it in a dream journal. Writing things such as this down quite often put things out in the light where it makes sense. Annalyze what is going on in your life at this time and see how it relates to your dreams.
I am not a psychologist and this is far from professional advice. It is from personal experience.
I do VERY MUCH believe in psychic dreams as I have had them quite a few times, but I feel this is not the case concerning your dream. the chances of U actually being in a Dog Day Afternoon scenario are almost nonexistent in this day and age unless U happen to live in the middle east or something. I am assuming U do not.
Sorry if I sound blunt here. Just doing my best to help. Please LMK what happens. I am sure everything will work out fine in the end. =)
