To start off with, if it was January of this year, your mother died, that is n ot very long ago, so naturally you are still grieving.
And to answer your question: yes, I still miss my parents - my mother died in 2002 and my father in 2009. Since then both my sister and my husband have died and I miss them too.
I also find myself occasionally dreaming of my grandparents and others of their generation, most of whom died before I was 14, and I am coming up for 73, now.
We loved these people, so yes, we think of them, and sometimes it hurts, like when you hear their favourite Christmas hymn or suddenly find yourself thinking, " Daddy would really have appreciated this joke." or some such thing.
