My heart reaches out to you as well. It can be a good thing when a cat returns in a dream, as I found out myself. My dear Milo showed up in a dream about a year or so after he passed away and it was like we had extra time to be together again. I woke up feeling so peaceful and happy, having had one more time with him. May you have similar dreams about Omelette and I hope she doesn't make you wait so long.
