Are bad dreams an early pregnancy sign?

Hello all, last night I had horrible dreams of my Brother dying and my husband going missing. They were so bad that my husband, who sleeps deep, woke up to my cries and whimpers. I talked to my husband and he said that that's a pregnancy sign. I took my Clomid, ovulated and followed the doctor's timing instructions. I'm due on Thanksgiving so I may be. Has anyone else had this happen? I've also had a few other sptoms like nausea, constipation, acheyness in my uterus, etc.
