The dream clarification

Almost a month ago I had this dream:

A Dream, in the room with two beds. I am laying on one bed and looking at a couple, laying on the other bed, he with his back on the top of her, placing his head on her chest, a kind of watching-TV position. Next, he takes a small revolver out of his pocket....At this moment I got a bit panic, realizing, that either he'll shoot himself, her, or me - how clever I was :o ....but in the next instant I just remained watching, knowing that it is the best I can do at this moment. He shoots himself right there,in his head, causing a slight change of the dream scene.
It is the same room, I am standing in the middle, where is a table behind which the man is totally out of control bouncing from one side to another, but obviously not dead yet. And I knew he will not be dead. That woman, helplessly, was trying to do something, crying, but all that she did looked like a dance of desperation around him. And than I realized, that the man I am looking at is me. Probably it's also not that shocking, but to me, this is for the first time I saw myself so clearly and without doubt it is me!! At that moment I became lucid, or very close to what I know is lucid; it felt like when one stands suddenly and fast and feels the blood keeping up with the rest of the body, arriving to the head, causing loss of common senses etc..
I kept on babbling to myself 'I am lucid...i'm looking at myself...I am lucid'. But I got interrupted when suddenly I am looking at my-sitting-self, a stream of water sprang from behind the shoulders and over the head, lightening. I had a strong urge to drink it, but the dream dissipates then and I wake up.

I want to add, that recently I'm going trough the breaking of a relation with my girlfriend and this bumped into it with amazing power and clarity of it's meaning. The meaning itself is less relevant than the fact, that it occured after several days of me asking over and over again the same question: Is it really over?...
