You said "I would really just like the dreams to go away."
Here are a few non-professional ideas -- no guarantees.
1) Perhaps you are supposed to inform other people about the situations in the dreams. So, tell us here, anyway. Also contribute to some other 2012 forums. Have you told your family and friends -- never mind the odd looks, they will soon learn!
2) Do you meditate, ask for guidance, etc?
3) Page 275 of the book Energy Medicine
by Donna Eden has a procedure "How to Restore Peace After a Bad Dream". It refers to other parts of the book also, but I'll give the main points. Start seated comfortably, relax any tense muscles, imagine a pleasant scene, and breathe deeply but not forcefully. Then do the following movements:
a) With thumbs on the temples, stretch the skin of your forehead with your finger tips, from center to sides four times. Then continue likewise starting from the front hairline, crown, back of head, and rear hairline (stretching scalp at each location).
b) With one middle finger between the eyebrows and the other hooked in the belly-button, push upwards with both hands. Use moderate pressure. Hold for 30 seconds.
c) Hold the following two points on each side of the head, one hand on one side and the other hand on the other side, for one minute each pair: (i) directly behind the center of the ear and at the base of the skull, where a slight depression is at the side of the main neck muscle, and (ii) above the eyebrow, three-quarters of the length from center to the outside end, at the hairline.
d) With your hands wide open, slowly and deliberately pull the energies down your legs, beginning at the sides of your hips. Draw the energies off your feet and finally rub your feet and toes.
3) Prepare as much as circumstances permit -- physically, emotionally, and spiritually (especially the latter).
4) Read some books and/or Internet sites that stress positive outcomes of The Event. Read the material and references in the Ascension topic at http://planetxtownhall.com/index.php/topic,1105.msg13471/topicseen.html#msg13471
