Well, if you get past the rush of emotions, you should maybe take a bit to outline the dream out, so it can be your next novel. That sounds like an epic novel, doomed to be forever compared to Gravitiy's Rainbow.
I'm impressed with that statement. Writing down dreams involves 1) remembering them; 2) having a writing tool at the ready next to the bed before the dream fades; 3) being committed to doing it. I do believe you can train yourself to do it well. I went through a period in my 20s where I wrote down every dream. After a while, you can see patterns. As soon as you see the patterns, you can control them. Eventually you can solve your problems (anxiety, repressed emotion, etc.) in your sleep. I don't know if my last statement is a true statement - but it would be nice to think so.I write down most of my dreams down no matter the scenario.
When I was around 15 I used to write down every dream I had no matter what. After awhile lucid dreaming just came sort of naturally (I could control dreams for seconds before waking up), and after maybe 6 months of that I could stay conscious in a dream for a little while. What an experience it is, and I would recommend trying it to anyone that wants to do it. Now the reason I write my dreams down is sometimes I dream some pretty cool stuff that helps with my writing, but honestly I may try to get back into lucid dreaming.
