Dream about pregnancy

My husband and I have been trying to get pregnant with out second child for a while now. My last period was in August. And I have taken 3 or 4 pregnancy tests all come back negative. I do have a couple of symptoms that I had from my first pregnancy. But still negative tests. I had a very vivid dream that I was pregnant and then had a healthy baby. Is my subconscious telling me to take another test? Is it telling me what I want to dream? Obviously, I don't expect that anyone will have an answer to that. I guess I'm trying to find a light at the end of the tunnel... Anyone else been in this boat? I hope I'm not alone.
