Pregnant dream

My aunt passed away almost 2 years ago, I still think about her a lot. she was the best. but ever since I got pregnant this is my third. I have been dreaming about her most of the time. I don't know if that means anything or maybe trying to tell me something. has anyone dreamed of someone they lost.? when I found out I was pregnant with my first my grandpa died that week. when my second one was born my uncle died the week after. so I am a little concern why I am dreaming about my aunt this pregnancy?
