I know what you mean. I have dreams, too...and I wake up feeling horrible. In the dreams, I almost believe that his suicide was the dream. Waking up and reality hitting me in the face is not fun.
I've now had almost 3 days in a row where I've dreamt about him. I've never dreamt these many days in a row about him. In one of the dreams, I asked him why he killed himself, and then he tried to strangle me while telling me, "it's your fault!" Other dreams were less dramatic, but still quite upsetting.
I don't know what to say, except that time will probably take care of these dreams. I have been extremely weepy these past few days, because of these dreams. And, anyone who says, "well, they're just dreams" obviously has never experienced it themselves.
Time. Just time. We just wait it out.
